PWS MK116 Mod 2-M

[Music] hey guys welcome back so today we're out of the range with some ar-15s now this is my standard BCM this is a rifle it I've had echo triggers in I've shot the snot out of I love this rifle it's pretty much just a standard recce 16 this one does have the older keymod rail system on it but I have a trick on patrol red dot sight on there this is just kind of way I like to set my rifles up in force light at a 45-degree angle it's just a simple rifle but it's direct gas impingement now if you follow the channel you'll know or if you even follow me online where we have discussions about things like direct gas impingement versus piston driven rifles you'll know that I'm a direct gas impingement type of guy when it comes to ar-15s the rifle was designed around it the rifle has a very low recoil impulse and a lot of that has to do with the design of the rifle and the bolt carrier and we'll talk more about that in a few minutes so I've never really been all that excited about many of the gas piston rifles that have come out over the last couple of decades most of them though have been short stroke gas piston z' which would be similar to an FAL or an SKS if you're familiar with those rifles well PWS has a gas piston ar-15 that's a little bit out of the norm it uses a long stroke gas piston designed much like the ak-47 so Jason's had an earlier version of the rifle for sometime PWS sent me one of their current m1 16 mod 2's to try out to see what I think of it and see if it compares favorably or not to my direct gas impingement rifles so today is the first day out with this rifle we're going to get 0 take a look at it talk about the basic differences between the PWS system and the standard direct gas impingement and today is just for me to get familiar with the rifle we'll do some more extensive testing down the road accuracy stuff like that to see how that gas piston system may affect accuracy if it does at all so we're going to start off by just dumping a magazine us on five five six then we're going to grab that PWS rifle and do some shooting with it if you take a look at how that rifle shoots it's extremely flat very little recoil very easy to control and yeah it's just a great all-around rifle let's take a look at the long stroke gas piston PWS this is the PWS this is the mark 116 mod 2 M this is one of the current generation of rifles and I will show you Jason's rifle here in a little bit that he's had for a while but this one has a textured upper and lower receiver it now has an AM be bowl tree lease and we have ambi mag release on it which is over here and you know ambe's selector levers and out here we have an M lock rail that's lightened he has a key mod version but it still has the adjustable gas regulator right here and we have a PWS style brake on the end if you've ever used these brakes or if you've shot a scar you'll know that those brakes are fairly effective it really helps tame the recoil of the 308 and the scar for such a light rifle but we'll go over more of the details about some of the features of this gun that are kind of unique but also proprietary but first I want to show you how it looks being shot as compared to the BCM I'm shooting the exact same ammunition and I'm going to shoot at the exact same target and have some fun now with this rifle which again features the long stroke gas piston so having just shot these back-to-back I would say that the recoil impulse is uh is comparable I think this one maybe on its current setting just a wee bit over gas because I can feel the the bolt carrier definitely coming to an abrupt stop and going forward where it was a little bit more muted on my BCM but this does have an adjustable regulator but other than that and I can't say it was a stark contrast difference I can't say that this thing definitely kicks more it doesn't it shoots very very flat but it has a slightly different feel to it all right so let's tear this gun apart and start talking about some of the features of this PWS rifle and show you the differences basically in the design of the long stroke piston and how that contrasts against the direct gas impingement let's take a look at the direct gas impingement system of the BCM and then let's take a look at this pw s so taking the DI gun apart most of you are probably familiar with but I'm gonna go ahead and take it apart magazines out of it chambers empty I'm gonna ease the bolt home and go ahead and pop my to takedown pins out and set the lower aside because there's not much differences there between the two guns now to take the DI gun apart all you do is pull your charging handle to the rear pull your bolt and carrier out drop down your t-handle and that's that now of course most of you should already know this but across the top of the barrel here you can't see it because the handguard but there's a little silver gas tube there's gas being tapped off the barrel and then gas is being read averted back down into the upper receiver where that gas comes to is this gas key on top of the bolt carrier so the gas comes then goes down a little hole travels down into this little expansion area where these two vent holes are and when the bolt is in lock up the gas will come down go into here there are piston rings inside there to seal the gases the gases come down and they're expand and then the bolt and carrier spring apart from each other and that launches the bolt and carrier rearward into the recoil spring which then extracts and ejects than that big spring pushes it back home into battery and the process starts all over again now the genius behind the direct gas impingement system is that you're not technically hitting the top of the carrier with this key you're just diverting the gas down into the expansion area and all those forces take place right here where the gun or the Bolton carrier I should say move back and forth in line with the barrel of the gun okay so you're not tapping it here causing the carrier to tilt you're having a direct springing apart action taking a place where the bolt and carrier pretty much moves straight rearward which gives the ar-15 it's very controllable recoil impulse now a lot of the gas piston guns in the past have used a short-stroke piston and what they've done is they'll take the gas key and cut it off they'll have a little impact nub up here and then instead of having gas coming down you'll have a steel rod that's acted upon by gas further down on the end of the barrel but it'll push that rod back it'll hit the top of the carrier on that the face of that little impact area the tappet it'll hit on top of the carrier the carrier naturally wherever its balance point is it's a little fulcrum it's going to hit on the top of it and want to push the carrier back like that and that's what they call carrier tilt so when you hit on top of it versus having gases and pressures pushed directly back in line like di when you hit up here it naturally causes the carrier to want to tilt and that carrier tilt has caused issues in the past with gas piston ar-15s and also causes a weird recoil impulse and can cause accelerated wear alright the PWS system seeks to change all that with its long stroke gas piston alright so let's take a look at this one again the magazine is out the bolt is back in the chamber is empty I'm gonna go ahead and let that bolt and carrier go home I'm gonna pop my to takedown pins out now I can pin this lower straight onto my BCM yes it's an e and B lower but aside from that it's just pretty much a standard ar-15 lower alright I don't know what's sticking for you see your buffer spring and everything inside right there okay so I'm gonna set this lower side now one thing you're going to notice right away is when I push this carrier in notice how it wants to spring back out I'll show you why here in a second that makes reassembly just a little bit different because when you try to close when you hinge the upper and lower down this will whack the top part of the buffer extension tube it'll it'll whack out to like push it in and close it it takes a little while to get used to that spring in there but when you want to take it apart you just pull rearward like you would a standard DI gun but now I'm gonna pull my bolt and carrier out slide it back a little bit and grab my T and I'll take it to its takedown position if I can and this is one of the things that don't like about the system is that it's a little bit more cumbersome to take apart okay so I'm gonna set the upper assembly over here for the moment and let's take a look at this so when the t-handle is traveling over the gas piston and until you disassemble the gas piston the t-handle is trapped by it okay but that's your long stroke gas piston arm all the way up here's we're venting gasses off it's acting upon this just like an a K and pushing the whole mechanism rearward now you can see on the top here you can actually see a tube that runs above the barrel itself and this piston rides in that tube so even though gas is acting on the piston all the way up here and pushing back it can't technically tilt much because the tube that this piston rides in keeps it from moving very much at all so it's still going to push pretty much straight back versus what would happen with a short-stroke piston to get your t-handle off you have a two-part gas piston and there's a flat cut into the piston and I just got to rotate it till I see the flats and once I find the flat I can separate the two pieces of the piston now my t-handle will come off so again I don't know if Jason can get in close and see that but there's a little there's two flats like look like wrench flats and to put it together you line it up with those flats pop it in turn it a little bit and now it shouldn't come off now the problem I'm having is this piece just keeps falling off sometimes when I go to put it together if it rotates to the right position this will just pop off I've had the piston just flopping around down in the gas tube so Jason says he's never had that issue but several times today while playing with it I've had the issue so that's in essence the difference between the two systems now if you take a look at an ak-47 you're gonna see the similarities here's an 8k obviously this is much bigger and more robust but you can see the similarities in the system just miniaturized and made to work with the ar-15 now you can take this bolt apart which I'm going to do is right now for you guys really quick I'll go ahead and take the piston off and now you have a cotter pin that's just like a standard ar-15 you can use the tip of a bullet this is a PWS tool used to adjust the gas I'm just gonna use it to pull the cotter pin out and once you take that out you're firing pin just like an air cleaner if air 15 is going to drop out and now you have a cam pin which you're gonna rotate that will clear the gas piston arm and then the bolt will come out now inside there there's a spring so you can see there's a few more parts to this mechanism let's play around the gas system on the rifle now what I have here in my hands is some American Eagle XM 193 this is basically the exact same ammunition that would be issued to US military it's the 55 grain ball load and it's surplus and a commercial packaging I'm gonna go ahead and load the rifle up and I have the gas setting had the gas settings set to standard so this is the way it would come from the factory you can see a big circle up here and this is its standard setting and it should work with pretty much any ammunition type now if you look on the side of the receiver it says 223 wild and for those of you that don't know what 223 wild is it's a chamber type that's presumably safe for you know five five six and 223 and give the optimal performance with both or some out there that believe that five five six is not safe to shoot out of the modern to twenty three barrel and there's all sorts of debate about that but this has a 223 wild barrel in it so five by six is safe alright so we have it on standard set him on fire a few rounds I'm gonna use the tool and turn the gas setting down one two it's softer setting alright alright so that was fifteen rounds you can see the guns ejecting nice and easily and smoothly I'm gonna go ahead and turn the gas system to its second position which is two holes that you won't be able to see and this is designed for hot ammunition like what we have in the gun right now and it should reduce the recoil impulse a little bit that bolt and carrier won't bottom out as abruptly and let's see if the gun cycles that is really really interesting guys you can definitely feel the bolt carrier not coming all the way back and bottoming out like it was with the other gas setting it has it completely and more mild recoil impulse and it seems to work just fine with the m193 ball all right won't need that now let's try some tula this is some steel case fifty-five Green Tula its labeled as 223 Remington which would be lower pressure than five five six I have some of that and a PMAG right here alright now we still have the gun on the soft setting okay I'll see if the gun cycles alright so click no bang but it kicked out the spit case just didn't grab one from the magazine click no bang and go ahead and chamber around put the weapon on safe and now I'm going to go ahead and turn the gas setting back to its standard setting all right let's see if it works with steel there's only 20 rounds loaded right works just fine locks open on everything now one last test we have some wolf gold which is 223 Taiwanese and most the say munition can be found over on lax ammunition that's where we get our ammunition here on the channel like to thank the folks from LAX for providing the ammunition to the channel we have the wolf gold loaded into a PMAG and we have it on its standard setting and I'm going to go ahead and turn it down one - its soft setting so this would be standard brass case 2:23 ammo let's see what we get you can see how the empties are just barely making it out but it's cycling I'm gonna go ahead and turn it back up to its standard setting okay so once again with that light setting it's so gentle you can feel the bolt moving inside there and on it's full gas setting it tells just a little bit over gas but works reliably that's how the gas system works so if you're looking to buy an ar-15 you want that Lego gun so you can do all sorts of crazy modifications to it down the road this might not be your best first option first of all it's not inexpensive but secondly pretty much everything from here forward is proprietary and of course that would make sense because it's using a long stroke gas piston versus a direct gas impingement system but just know that there are a lot of differences we're gonna go over from this point forward now there's some differences back here but these are differences that pretty much you can apply to any other ar-15 and it will go ahead and point out before I forget this is a BCM stock and BCM pistol grip that's on the rifle that's why I feel so familiar to me when I shoot it because I'm so used to the straighter grip of the BCM gunfighter grip and then I like to be see'em stocks alright so let's start out here on the muzzle into the gun I believe there are different rail types that are available this one has a 19-13 rail that runs all the way across the top of the rail itself and then here we have nineteen thirteen rails where you can put devices out here like flashlights or whatever you want and then em lock so it's kind of a hybrid rail then we have em lock on the bottom as well it's also well ventilated you can see some large cooling holes that are cut into the rail itself this is a PWS muzzle device and this wrench flat here is even different like if you take a Magpul mat a wrench and try to get this muscle device off it doesn't fit this flat and it seems like PWS is just everything just a little bit to their liking for this rifle but movin rearward we have you can if you can see through the rail here you can see how the barrel has an interesting profile so it's it's it's not a pencil weight barrel by any means but the gun still feels pretty light in the hand and points nicely it's a fairly thick barrel but then it tapers and gets more broad right about here and then this whole area is where we have the gas block for the rifle in its operation so if you look at the top of the rail you're gonna see a hole cut through and this is how you would adjust your gas system now they have a key that's available for it but you can also use the tip of a bullet to make adjustments now you'll also notice right here in front right next to the gas piston adjustment just below it there's a nut this nut is proprietary this nut is threaded and this is what's holding the gas block onto this proprietary barrel alright so if you're gonna look at trying to swap out barrels on this gun you're not going to be able to pick up a standard ar-15 barrel and just slap it on here or just slap this gas block onto a standard ar-15 barrel and go out and shoot not gonna work it's all proprietary alright so let's talk about the adjustments of the gas system now right here where I'm pointing with the tool you're gonna see a big circle so this is the standard setting now this one's different than Jason's gun which is an earlier model which had four settings and this one only has three all right so this would be a wide-open standard setting and this is probably what you should run the gun on most of the time you can turn stick the tool in and turn this and now you'll see two little circles and this will reduce the gas flow just a little bit so if you have really hot m193 ball or m855 ball the guns still gonna cycle but it's gonna have a muted recoil impulse and what I've noticed when I fire 193 ball out of it is that it doesn't feel like the carrier's bottoming out it doesn't feel over gassed but if I put something like Tula in it the gun simply isn't going to cycle whereas a wood cycle in its standard setting okay and then the last but not least we rotate it all the way over here and you have three circles and that would be for your suppressor settings so it restricts the gas flow heavily put a standard but a baffled can on the end of this gun and this is the setting that you would want to use now there's a pin that prevents this from turning any further than these three settings no matter how hard you try so I'm going to go ahead kill this spider and then rotate it back to its standard gas setting so it's very easy to adjust the gas on the rifle but you shouldn't have to do that once you pick a ammunition that you like to use and whatnot set it to what it uses probably the standard gas setting and just leave it alone unless you suppress it now if you come further back here you have of course this this proprietary rail system that works around the gas piston tube that's up tucked up underneath here underneath this 1913 rail and here it mounts now I haven't had this rail off but I'm gonna go ahead and guess given the diameter of this gas tube that it has its own proprietary muzzle or I'm sorry a barrel nut here as well so everything here is going to be proprietary to the rifle now moving back we have some interesting lightning cuts made to the receiver the upper receiver here we have a magazine release and B so when I push on that you can see how it releases the magazine have a standard ping-pong paddle for a bolt hold bolt release and then here's our fire control on the mark 116 you're going to notice that it has an NBC when I pull back on this claw it releases from either side has an Ambu charging handle and this is a PWS charging handle you can see their logo there and then one other interesting component is the castle nut now you can take this castle nut system off it's not proprietary to PWS you can put it on your ar-15 if you would like to one of the things you'll see people complain about quite a bit is the fact that a castle nut isn't staked and if it's not staked it could potentially back off and so you know if you use lock tight and stuff I've never seen a castle nut back off but there's some guys out there that claim that they've seen it but this system does away with the need for staking and you'll see the little teeth here and then down here you have a little QD mount but inside the QD mount I'm going to point to it right up inside there you have a little detent and that detent acts against these teeth so it's gonna ratchet as you tighten this you're gonna hear it click and then in theory that replaces the need for staking the castle nut and that's pretty much it guys you've seen the gun inside and out and over here I will want to point out as well of course you have a standard port cover no forward assist and if I want to lock the bolt to the rear with guns like the LWRC or something like that you have the ability to to lock the bolt not just release it but lock it from the right hand index finger with this gun you can't pushing on this does nothing and pushing on the front of it does nothing if you want to lock the bolt to the rear you still have to use the ping-pong paddle on the other side of the gun hold that down lock the bolt to the rear and then if you want to release it it sets here just behind the dust cover you just reach up with your finger push and it will release the bolt okay so I think I've pretty much covered off on everything the gun has there's one other piece here that you might find interesting inside you have a standard ar-15 trigger system and it may even be a BCM trigger I'm not sure it kind of looks like one but right here by this I'm using the PWS tool here gas adjustment tool but right down the side there you're gonna see a little white piece of plastic that's a plunger and spring system and it's a really really heavy spring and what it's doing is pushing up on your rear locking block pin hole alright so when you go to close this see that little gap of light right there I have to push down see how it springs back it's a built in a Q wedge alright so when you push down on the upper and pin it that's applying upward pressure which makes the gun feel very tight like I said it's basically a belt built in a Q wedge alright I think I've covered everything on the rifle all right guys we're starting to lose sunlight but we've been out here for about three hours shooting this thing talking about it taken apart learning everything we can about the gun now I want to point out that I didn't add any lubricant to the gun one of the things that's unique about the direct gas impingement system is that it applies carbon to the inside of the rifle a lot of you guys think that's a negative but in reality it's a dry lubricant one of the things that a gas piston rifle like this denies the ar-15 is that natural carbon lubricant because it's venting most of those gases out here but the gun runs just fine and we've had no malfunctions with the gun assuming of course we had the proper gas setting for the ammunition we were using but just running this thing in standard mode it runs great you can see some discoloration we got this thing smoking hot this rail really does a good job getting rid of the heat yeah even with my BCM we were doing some suppressor testing recently after nineteen rounds it was too hot even with the heat shielding if I touched any part of the middle handguard it was too much it would burn me and we've been shooting the snot out of this thing and while it's warm it's not burning me whatsoever you can see on top of the barrel here I don't know if Jason can see it I'll get a picture of it there our vent holes in the gas tube the tube runs all the way back to the receiver that the piston rides in and it vents gas off along the way you can see where it's impacting the barrel you can see where the gas block is it's nice and big but I was shooting it with my hand up here next to the gas block and I wasn't getting any burns or anything like that from the gas system which was something I was concerned with you know I don't you don't have to be concerned with that even with this really open handguard so everything about the gun seems to work the only thing that's a little quirky for me is the disassembly and reassembly but the gun has eaten at least a case of ammunition this afternoon of everything from steel-cased m855 ball zqi wolf gold american eagle x m193 and we've had no issues with the gun so color me impressed and the testing will continue next we're gonna put an optic on this thing a magnified optic and do some accuracy testing with it with just some standard you know like wolf gold which is kind of standard standard benchmark for us here and then we'll put some match ammunition of the gun see how it likes it but so far guys yeah this is really really interesting to me and i'm enjoying shooting the rifle the guys at PWS sent me this rifle to test I didn't purchase it but if I decide I like it I want to keep it I can purchase it for dealer pricing so we'll see if I decide to keep the gun or not I'm gonna do some more testing with it but yeah I didn't think I was going to warm up that much to a gas piston AR but this one definitely has my interest Peaks on the continued shooting it guys if you have any questions you can ask those questions down below if you'd like to support us here at the military arms channel the best possible way to do that would be to become a patreon supporter we don't take money from P WS CZ Remington anybody we don't get paid by anybody but our viewers we're 100% viewer supported patreon.com check it out and consider becoming a patreon also if you'd like to pick up a t-shirt from forge from freedom that's another way to directly support us here at the military arms channel there's a link down below to both patreon and forum forge from freedom pick up a t-shirt from the Mac collection that supports us and last but not least be sure to check out copper custom gonna run this last magazine out of the gun and put it away I don't think I'm gonna clean it we're just gonna keep shooting it and see how dirty it gets and see how she functions thanks for watching guys we'll talk to you soon
