CMMG Mk57 5.7x28mm AR 15 Review

the CMG mark 57 let's check it out [Music] [Music] [Music] FN developed the five-seven caliber in 1990 and the purpose behind it was to replace the nine-millimeter as the sidearm and also this is a close and personal personal defense weapon it's made to defeat body armor up to type 3a and even ballistic helmets it was designed as a military caliber but really gained a lot of popularity in the civilian market this is the CMG mark 57 which is in 5.7 by 28 millimeter it's a really high velocity round and there are a lot of advantages with a57 I'll tell you guys CMG just comes up with some really cool calibers and I know when I was at NRA and I was in the CMM G booth talking to those guys when I first heard they were coming out with the five-seven I just thought that was the coolest thing I mean it's just a really unique caliber and it does offer a lot of advantages but you know their compromises with everything doesn't matter if you're you know touchy you can't really compare this to 223 but yet you can't compare it related nine-millimeter it's kind of an in-between caliber between those and that's what it was designed for it was designed as a personal defense weapon more along the lines of obviously what the US Secret Service is using it for for a caliber that can really do a lot of damage up close it's got a high velocity but yet the penetration is not over-the-top that's one of the things about 5-7 by 28 that's really appealing does it have its limitations yes and we're gonna look at those we're going to talk about them but there are a lot of cool advantages but first remove the magazine it does take your standard fnh magazines in a course it comes with one Pro mag it's a 20 rounder and they're polymer that make sure the chamber is empty and it is now here we have the 5 5 6 or 223 and then we have the 5.7 by 28 then we have 9 millimeter and honestly it fits right in between these two you get your longer range you get your higher velocity with the five five six we're going about three thousand feet per second with a 62-grain bullet here we're going about 2,000 2,200 feet per second with a 40 grain bullet and then we have the 9 millimeter which is a 115 grain going at about to 1,200 feet per second so even just those numbers show you that that the 5/7 is right in between we're talking about out to about 200 yards which of course the 5/6 can go beyond 500 rounds plus so that gives you a lot of effective capability but the recall is more you have less recoil with the 5/7 and then the 9-millimeter which it was really designed to kind of replace it gives it a heavier bullet with the 9-millimeter but your effective range is longer with the 5/7 but again they're over 14 countries that use the 5/7 and there are a number of law enforcement agencies here in the US and the US Secret Service that are going with the 5/7 but one caliber that is really close to the 5/7 is the 22 Magnum it has a lot of the same characteristics ballistically so you have a little bit heavier bullet a little lower velocity with the 5/7 and to me the the biggest plus for the 5/7 over the 22 Magnum is that it is a centerfire caliber and that means it's going to be just a little bit more reliable now guys there are a lot of arguments about the comparison between these and the effectiveness of the 5/7 but for quick down and dirty that's pretty much what the 5/7 is about now we're gonna go over some of the details of the mark 57 which are different than a lot of other options out on the market first off of course you have your standard ar-15 upper it's 7075 t6 aluminum the lower I mean it's up to mil spec they're just excellent quality I've dealt with CMM G for a long time and they're just good good products the handguard is one of their proprietary hand guards it is em lock it's a 7 inch and then we have the 8 inch barrel with an a2 birdcage which is half a 28 threads so suppressors will be able to fit on there very easily and then of course there is subsonic ammunition available it does have the lower which is a pistol caliber lower then we have the magazine release which has become standard for a lot of your pistol caliber lowers and then of course a flared magwell like I've said it does come with a pro mag 20 round magazine and and it works fine we have a great success with those magazines out on the range but one of the things that it doesn't do it doesn't drop free with the fnh mag it's made a little differently and it will drop free and then we had the 30 round pro mag this one was it functioned fine but then again we had a few difficulties and we're going to do some more testing because it was only a couple of rounds that we had problems with and I just really want to test these out a little bit longer we'll do that in the next video but this will give you 30 around capability a pro mag sometimes can be hit or miss but they're 20 rounders work fine now does come with a standard mil spec cm mg trigger comes with ammo pistol grip from mag pole standard charging handle and it does have an ambidextrous sling mount on the back being a pistol they did include one of the shock wave technologies blades which I really like this and then of course a milspec buffer tube this is also offered in the Banshee configuration which is a 5 inch barrel very short handguard very small package and they do make it as a short-barreled rifle again and you can get a pistol of course here I have one of the primary arms Cyclops 1x prism scopes I love this but I really wanted to test out accuracy to make it fair I installed one of the 1 to 6 primary arms acss predators in this way we could really test out the accuracy at 50 yards now the first group for the day on target this was deciding the rifle it came in right here a nice little tight group this was at 50 yards and then we moved the scope over and got a four shot group and that was definitely user error and then another group of 50 yards now there's some features inside that really make the difference now this is the bolt carrier group that's in the mark 5 7 and it is a radial delay blowback and what that means is is when the round is fired the actual gases push the bolt in the rear position just like this it gives it a delay in unlocking and coming back but one thing that it also does is it pushes the bolt back forward and so it just really is a great revolutionary system in fact this is patented by CMM G it also allows for the bolt carrier to weigh less and you can see the relief cuts they've made which make this easier and softer shooting and that's one of the secrets of whatever pistol caliber carbine that you can get from CMM G whether it's nine-millimeter 45 or you know whatever but that's one of the secrets that keeps this a really soft shooting firearm this is your standard m16 bolt carrier group and the bolt actually cams and then pulls back out there's no spring action and then of course you have your gas key here which is pressured it's the gas coming from your gas tube that pushes your bolt back and this too also allows for a lighter weight buffer and if you're going to shoot suppressed they even have a special buffer that's even lighter than the standard again you do have your standard milspec trigger which can be upgraded if you want to you can see the system that's built around the mag well we're just gonna release the mag a little bit just to kind of get a better look but you can see this area is machined it's just a very well designed ar-15 now CMG was kind enough to send quite a bit of different ammunition for this review today though for the first look we're gonna be mainly focusing on the American Eagle and just getting some basic function test accuracy things like that heading down to the range of course the radial blowback action made this a super soft shooting firearm you know even though it is an intermediate caliber a lot of times would blow back there can be a lot more violent action coming back and give you that recoil but it helps to mitigate it with that delay in the bolt and so it just makes it a real pleasure to shoot as far as the reliability we had no problems with either the pro mags or with the fnh max the twenty rounders when it came to the 30 round magazines from pro mag we did have a few issues in fact I'd already heard reports that there had been some problems but we had very few problems and I really would like to test that out more to see you know if it's just that initial effect but I think we had a couple of rounds now one thing that was really funny and I'm gonna show it right here in the video when I loaded the magazine the round actually the first round popped up and when I closed the bolt it pushed that bolt into the chamber I was surprised that I didn't get a double feed and it just fired like normal he just fired the magazine about half way through and then I had a malfunction and that was the only malfunctions we had and it was with the 30 round pro max all right you can see where it kind of jammed up right there so not really but that's two out of all 30 and that was the last round so we're gonna do some more testing and as far as accuracy goes we were testing it at 50 yards and man it just really had tight groups this is really a great rifle going out to about a hundred and then with the 8 inch barrel you can get it on out to you know 250 300 yards really effectively about 200 yards is you know where you want to kind of keep it in but again this is designed as a personal defense weapon you know you're you're not gonna over penetrate let's say in a home defense scenario but it is a very light bullet so that does need to be taken into consideration rubber dummies is one of the best training tools on the market and you get a 10% discount using suit zero zero when you click the link down in the description now one of the big advantages of the five-seven is that there are so many different specialty ammos of course you've got your standard American Eagle and we're mainly going to be shooting that for this first look but we have some of this Vanguard this is called dragon Fang we're going to be doing some testing with it then we have some of this aren't our weapon systems this is these are self-defense rounds fully copper you can see that these things will expand I mean that is a really cool design on that bullet and then we have some of the elite ammunition this is the penetrator and they have some others we're gonna be testing those out and then also we're going to be doing some subsonic coming up as well and this is Detroit ammo company so we have a lot of different ammos we're not gonna be doing all this for this review but this is coming up really now one thing about 5/7 is the brass is fairly thin and it has a coating on it to make it really slick and it just helps for feeding and it gives strength to the case itself so if you're buying any kind of reloads or ammunition that's been manufactured with reloaded brass you know you need to be careful because it can cause weak spots and so just want to kind of get there we'll probably talk more about that in the upcoming video now CMG only sends 120 round pro mag which again work fine but I wanted to kind of test some different mags out and so I got in touch with gun mag warehouse and they were kind enough to send some regular F&H mags some extra Pro mag in the twenty rounders and some of the thirty rounders so we could test them out the fnh mags run $34.99 I believe that the pro mags run $27.99 see they are cheaper and then the standard 30 round pro mags are 32 99 so again we're going to be doing some more testing with these before you run out and bomb 20 rounders worked flawlessly they also have a 10 round ER and I want to thank gun Meg warehouse for sending these now as far as the pros and cons between 9 millimeter and 5 7 9 millimeters definitely a proven self-defense round and there's a ton of different choices out there but if you're looking for a good personal defence weapon something that's close that has a lot of capability the five-seven is definitely a good choice one of the big pluses though with the five-seven is its ability to defeat level 3 a body armor that's a big plus for a self-defense situation also the ammunition is a little bit lighter weight of course you know you are getting 20 rounds but again you know they're making the 32 round Glock mags and a lot of these so that's not really necessarily a plus for the five-seven it's really more of a plus for the nine-millimeter it is less recoil I mean it is a soft shooting firearm but another big plus for the five-seven is its ballistic capability out to you know around 200 yards in this configuration with a nine-millimeter pistol or carbine you're just not going to get that kind of range there are a lot of ammo choices for bow nine-millimeters gonna have more but I think for specialty ammunition the five-seven is going to shine but the 9-millimeter ammunition is definitely less expensive and it's more readily available most of your typical shops you may not find your 5-7 ammunition but you can find 9-millimeter but one of the great things about the caliber and especially in this configuration is that it is just such a joy to shoot there are a lot of different things you can do with it and again it fits in that medium role between five five six and nine millimeter you know am i try to talk you into it no you know the US military goes with nine millimeter in 5.56 but I think this is a great option and if you're really looking for something in the five-seven if you happen to have an FN five-seven this would be a great choice and it would really complement the system as far as price goes these are running a little more than your standard ar-15 they're thirteen hundred and forty nine dollars on the CMG website and of course it's your local gun shop you are probably going to get that for less but there's a lot of reasons a lot of the quality that goes into this with the 41 40 cm chrome moly vanadium barrel and also the 7075 t6 aluminum and the just the radial blowback technology that is proprietary to CMM G so that's definitely going to put the price up plus you're getting your surco finish and there are 13 different options for color so if this silver is a little bit bright for you there's definitely a lot of cool colors available also CMM G has a lifetime guarantee on their firearms and they're made in the USA right there in Missouri now guys one of the things about CMM G is they believe in social media and they send these guns out to different reviewers here on YouTube but one of the big things about that is is you're getting a lot of different perspectives so if you're interested in the five-seven just take a look and see some of the different reviews there's some really good ones that are going to be coming out and so again it really helps to keep the you tube gun community honest now I'm gonna think CMM G for sending the mark 57 for this test and evaluation and for their sponsorship these are great rifles all the rifles that we've tested and pistols in the AR form have been just superb from cm mg and so if you're looking for a really high quality rifle especially in a very unique caliber or even if you want to go with the 9 millimeter 45 in that radial delayed blowback action I think CMM G is the way to go just with the exceptional reduction in recoil of smooth shooting and their always reliable and I want to thank my daughter Sarah for a great range day and also for joining the team suits she's now going to be a permanent part of the suits channel be strong be of good courage god bless america long live the Republic [Music] [Music] [Applause] [Music] [Music] the CMG mark 57 in 5.7 by 28 it sounds goofy a 5.7 by 28 cm mg and it is superb it does have a use the standard now heading down to the range and we've got a lot of different ones to use [Laughter] you
