Midwest Industries 30 Caliber Muzzle Brake For Ar Style .308 5/8x24. Compensates muzzle blast and sound from .30 caliber AR style rifles. This device installs quickly easily and quietly by hand from the front of the firearm to the rear of the firearm. This new muzzle brake offers a chamber and porting system which allow gas to move around more efficiently rather than letting it sit in the rear of the bore where it builds pressure. The sides and upper part of the brake are slotted and beveled for a better fit and easier operation. Tests demonstrate that even under sustained chamber pressure the muzzle brake reduces sound and recoil considerably. This results in improved accuracy as the shooter gets on target more quickly and the muzzle brake reduces noise and blast associated with shorter barrels.
