Yes, the Precision Armament M4-72 Severe Duty Compensator is designed to reduce recoil and muzzle rise, making it a suitable addition for an 11.5-inch barrel AR-15. It enhances stability and control during rapid fire, which can be beneficial for shorter barrels.
The .308/7.62 5/8-24 M4-72 is compatible with the Sig 716I AR10. Do not confuse with the 7.62x39 M4-72 AK.
The .223/5.56 and .308/7.62 versions of the M4-72 do not come with a crush washer. The M4-72 AK does come with two crush washers as they do not rely on a crush washer for indexing as the AK uses a detent pin. Those washers are to fill the gap between the brake and the barrel.
No, this brake is only in 22 and 30 caliber. You would need a 35 caliber brake. Please see the Precision Armament Hypertap in 9mm/.350 available in both 1/2-28 and 5/8-24 thread.
When you remove the brake and shoot it does the rifle function as normal?
Generally it depends on the firearm you are putting the muzzle brake on. But questions regarding legality by state should be directed to local law enforcement.
The 5.56/.223 version's length is 2.250". The 7.62/.308 version's length is 2.275". The M4-72 AK version's overall length is 2.275".
Though technically the thread/caliber would match, due to the short barrel and the nature of a reverse baffle brake, the gas being redirected back may be found uncomfortable. Precision Armament recommends that this brake not be installed on any barrel less than 14.5". For short barrel applications, please see the Precision Armament EFAB or AFAB.
