Basics of Suppressing the AR-15

[Music] laws are rapidly changing more so now than ever it's getting easier and easier to buy a suppressor so we're going to do a short video and we're going to talk a little bit about what it's like to express any ar-15 and why you might or might not want to suppress one this could depend on what you do so first off let's talk about what makes noise when you pull the trigger on an ar-15 so things that make noise are going to be the hot gases as they exit the barrel you also have the sound of the projectile breaking the sound barrier as it travels down Lane and then of course the sound of the action itself cycling in the weapon every time you pull that trigger so let's talk about what the suppressor will not do it will not change the sound of the bolt cycling and it will not affect the sound of the projectiles that break sound barrier now to tackle those two you can use subsonic rounds of subsonic round won't break the sound barrier and will be quieter however it won't reliably cycle a standard ar-15 unless you do significant modifications to it in which case you're going to be having problems with standard ammunition so the most part most people use supersonic rounds now what a suppressor will do is it will cool the expanding gasses as the X of the barrel and a series of chambers that helps with that in that noise so when it comes to noise an ar-15 with the suppressor it's not going to be incredibly quiet a unsuppressed 16-inch ar-15 has a decibel noise level of around 167 decibels with the suppressor on you're looking at about 130 735 depending on altitude and a whole variety of other factors in the case of the short barreled rifle it's going to be a little bit louder so on my mark 18 with a surefire socom suppressor I get a decibel level of around 130 940 depending on a variety of factors so if you're looking for the Quietus weapon ever five five six AR is definitely not it that being said if you switch to a 300 blackout you can reliably cycle subsonics and that might be something that you want to do however 300 blackout does cost more so it's a little bit of a balancing act when it comes to that a couple things to think about when you're selecting a suppressor the short of the suppressor the less it's going to wing to be able to suppress noise and flash in that type of thing the longer it is the better it's going to do the heavier it's going to be however the heavier and longer it is a little less wieldy that rifle is because right now I have a six-inch suppressor on a ten point three inch barrel which brings my overall length to just over 16 inches but imagine adding that six-inch suppressor to a 16 inch rifle when you have like a 22 inch rifle so you need to figure out what you're going to be doing with your rifle and find a suppressor that's most applicable to your needs for example if you're mostly shooting long range hay a longer heavier suppressor might be better because you're probably going to be stationary for the most part if you're hoping to do some hardcore room-clearing look at those pissed bottles then a shorter suppressor might be more to your advantage or something along those lines so fine what works for you when it comes to a suppressor buying one that has a good mounting solution is going to be vitally important because there are certain mounting solutions that have been known to get the suppressor stuck pretty hard find one that works for you I'm not going to advocate for one or the other just do your research on that type of thing so there are a couple bad things that come along with mounting a suppressor to an ar-15 particularly so we're going to talk about that specifically we have heat to the suppressor we have the gas blowback and we have the bolt carrier speed so let's talk about how to solve those three issues so heat that's an interesting point so every time we fire the ar-15 with a suppressor mounted the suppressor is going to increase in temperature by about seven to ten degrees depending so imagine you put a 30-round magazine through that suppressor you're looking at around 270 degrees added to that suppressor it's getting pretty hot pretty fast what happens is as you fire around through the suppressor and keeps getting hotter and hotter eventually you're going to have a heat Mirage rising off the top of that suppressor if you're a long-range shooter and you're using a magnified optic that heat Mirage is going to mess up your sight picture on that long-range target for that reason a lot of people end up using some type of suppressor cover a suppressor cover is a covering that's heat resistant that wraps around the suppressor help get rid of that Mirage the problems with suppressor cover is that one it traps heat in there and two I haven't seen one last very long a lot of times they are heat resistant but a lot of times I see the melts through the suppressor or otherwise break down over time now if you're a high speed dude you're putting a lot of rounds through your weapon that suppressor covers not going to last long at all now I've seen a lot of people deployed using suppressor covers I haven't seen them last that long I could be wrong maybe there's somebody who's found a really good suppressor cover out there but overall I haven't seen them withstand some really heavy use and be usable for a long amount of time that being six months plus so heat and again the thing to think about is if you're working in transition with your suppressor it's pretty hot and you swing that down to your leg and bumps against your leg and you have a some pants that can resist that heat could burn a hole through them or if you have shorts on because your boss real g then it's probably gonna burn your legs as well I'm gas blowback in bolt carrier speed those kind of go hand in hand so because the suppressor traps all that expanding gas you have more dwell time at the gas port what that means is you have more time for that gas to flow back into the rifle which essentially makes it dirtier overall in that type of thing so what's going to end up happening is you have a lot of guests gasp exit out to the ejection port that can be a problem for left-handed shooters because that's going to be going directly into their face for our right-handed shooters the gas is going to be exiting out behind the charging handle now this is going to be dependent on the rifle barrel length that type of stuff but on short-barreled rifles it's especially pronounced so a couple ways to deal with that one you can get a suppressor with an expansion chamber to help reduce that that's what the surefire socom has that's the reason I got it because to some extent or another it was designed to be used with short-barreled rifles another thing you can do is you can limit the amount of gas that gets through the rifle you can use an adjustable gas block micromo makes some good ones there are a bunch of other companies so find one that's rated for several rifles if you using them or for longer rifles to make sure that's robust and I has good reviews on it but I would definitely recommend the micro MOA they have some really good products so by living that amount of gas you're going to have less gas in your face to have them further down on the bolt you can have to actually get a Bolton book excuse me a bolt carrier that is vented I think I believe it's gemtech that makes it and that will help get rid of some of that gas and finally you can get a charging handle that has a better seal and I believe it's a PRI gas Buster and that will limit the amount of gas getting to your face and again what does that gas do and gets your face Sting's your eyes makes you less situationally aware and it's going to affect your ability to shoot so that's always an option some people take some silicon sealant sealant and they make their own kind of little gas Buster charging handle that's always an option you can do that as well if you're handy so by limiting the amount of gas upfront either with an expansion chamber or with a adjustable gas block we can help reduce the bolt carrier speed however what most people do is they don't deal with the gas me included and they simply focus on that bolt carrier speed and slowing it down so there are a couple different ways to do that one of the main ways that most people are doing that is by adding a heavier buffer the heavier buffer does work to go so it's going to help slow it down however the solution that I found that I think works really well is a longer buffer shrink so in this case I want the bolt or a five system which is essentially a rifle length spring and buffer in a collapsible form and so that helps give the bolt carrier more room in space to slow down before it comes forward so that helps slow down control the really vicious recoil of a suppressed SBR I used to use a really heavy buffer and my rifle but I found that by moving to the bolt or system I can use a lighter buffer and overall it's a more pleasant experience so you might have to do a little bit of tweaking there if you go online you'll see a bunch of people talking about what buffers weights and all that types up with Springs they use so final it works for you based on your rifle because everybody's rifle is going to be different depending on barrel lengths suppressor type used and that type of thing and also an ammunition so make sure that you're consistent with your ammunition otherwise you might have to readjust your system with a suppressor on now a lot of this can be mitigated by using a piston type set so PWS you know the HK m are five five six aka the hk416 those are great systems and they work really well but for some people they don't like the way a piston system balances since there's a lot more weight up front and what's a suppressor added that's a lot more weight so it's kind of its kind of up to you what you want I prefer the DI systems and standard ar-15 but um be aware of the distance systems Dussault a lot of these problems straight up to that so we talked about a lot of bad things that go along with having a suppressor in arrival so why should you have a suppressor in your rifle well for one recoil reduction because it's diverting and trapping gas your recoil is much reduced and you wouldn't think it'd be that much I've seen figures that say it's anywhere from twenty to thirty percent reduction in recoil and with that reduction in recoil shooters tend to shoot better kind of increases the shoot ability of the rifle I found that I shoot tedder groups and I can shoot faster and more accurately as a suppressor mounted onto my rifle even though it's adding weight and making it a little bit more unwieldy now the suppressor isn't specifically making the rifle more accurate again rather just making a shootable just as a note of course you have sound suppression as one of the benefits of pressor it's not going to be hearing safe but coupled with hearing protection and the suppressor it's going to help protect your hearing for a longer period of time which is a huge benefit for me because for those guys have been shooting for a while I'm sure you can already see some of the effects of hearing damage from firing weapons with just ear muffs or in your protection on so great thing about having a suppressor finally one of the main reasons I mounted a suppressor my rifle was I was doing a lot of night shooting shooting under night-vision goggles without a suppressor the flash from the rifle will wash out you're an VG's it's very annoying so with the suppressor added it doesn't eliminate the flash completely but it makes it a lot better and finally if you're cool guy who's shooting a lot indoors and that type of thing then a suppressor is good to get through a lot rid of a lot of that concussive noise from shooting indoors which helps improve your situational awareness so again there are some reasons you might want to use a suppressor finally last reason is if somebody is getting shot out with a suppressor the suppressor actually makes it very hard to detect where that person is shooting from people who have been shot suppressor is often confused where the noise is coming from from about 90 to 180 degrees off so guys there are pros and cons of suppressors find out if a suppressor is for you I'm happy to answer any questions so feel free to comment and again the whole point is having a suppressor on or anything like that it's a little cool so make sure you look cool guys thanks for tuning in
