STD Simple Threaded Device Brake ReviewAfter realizing that my fun time blasting away with my AR15 pistol was causing the stock price of Tylenol to raise, I decided something needed to be done to tame down that insufferable AR15 pistol muzzle blast. Historically my prefered muzzle brake has been the PWS CQB which I find does a mighty fine job of the shooter perceived concussion of the blast on short barrels AR15 uppers and also delivers a braking effect as well. The problem is that these Krinkov and other similar brakes are usually well over $100 and I was in search of something less expensive, lighter and more compact. Someone suggested I get an STD - which lead into a whole different discussion. The STD or Simple Threaded Device does have a rather catchy name for a really cool little brake that actually works.
The makers of the STD Simple Threaded Device muzzle brake cite reduced levels of sound pressure experienced by the shooter. I am not talking about suppressors, or mythical acoustic disintegration devices, the STD is just a really simple little brake which is designed to not increase noise to the shooter.
The problem is that these days we all screw on most effective muzzle brakes redirects the muzzle blast to 90-degrees from the shooter instead of 120 to 180-degree like a normal bare muzzle would. All these really effective brakes effectively redirect the muzzle blast closer to the shooter and therefore making it louder for the poor bastards to the left, right, and behind the gun. The idea of the STD muzzle device was to create a brake that would effectively move/direct the muzzle blast as close to 180-degrees from the shooter as possible. The result is pretty surprising and extremely noticeable on AR15 pistols and short barreled rifles. The STD is not magic and there are compromises. It does not do a very good job with controlling muzzle rise, but really is not any worse than a bare muzzle. The STD muzzle brake is not a flash hider either and in fact can produce some freaking unbelievable fireballs out of really short barrels. The STD has one singular purpose which is avoid breaking your eardrums every time your gun goes off.
On a rifle length barrel it does this pretty well and in fact could be a really nice muzzle device for hunters which will take the occasional shot or two without ear protection. One .22LR rifles the report was really quite pleasant, but hearing protection would still be recommended in all situations. AR15 pistols and SBRs are freaking loud and there is no way around it without a suppressor. The STD just makes it a little better and prevents the report from gettting amplified by other brake or flash hider designs. Testing has shown that the STD can reduce shooter perceived sound pressure levels by as much as 3db over a standard bare muzzle - that 3db reduction makes it seem like the report is half as loud to the shooter. If you swap from a typical vented brake, most people will perceive they have cut the perceived sound pressure by four times.The other thing I really like about the STD is that it is tiny, short, light, and quite inexpensive. At around $60, the STD is one of the most affordable aftermarket brakes on the market and certainly one of the lightest and smallest. If you have an AR15 pistol this is an option the can bring the deafening roar into check.
