Precision Armament M41 Severe-Duty Muzzle Brake (7.62mm/.308, 5/8x24)

The M41 Severe-Duty is Precision Armament's radial-port precision brake for 5/8x24 rifles. Three large axisymmetric baffles, each with five helical ports, vent gas counter-clockwise around the bore, which reduces recoil and the torsional kick of heavy bullets in fast-twist barrels. Because the venting is symmetric it needs no timing: torque it to spec and it is done, with no shims or washers.

This is the 7.62mm/.308 bore version, machined from HTSR 400-series stainless in DLC matte black or bare stainless, with Class-3+ threads cut in the same operation as the bore aperture. Precision Armament says measured performance is very close to the M11; the M41 trades the M11's closed bottom for symmetric ports, so it lifts more dust when shot prone.
