Overview
The M11-SPR (Special Purpose Rifle) is a compact, lighter version of Precision Armament's M11 for precision AR-15s and long-range varmint rifles on the standard 1/2x28 thread. A large symmetrical blast baffle and compensated forward baffles manage recoil and muzzle rise, top ports vent upward, and a deep recessed crown protects the exit aperture from impact damage. The threads are machined in the same operation as the bore aperture so the brake sits true to the bore.
It is 2.225 inches long, 0.750 inch at the barrel, and 3.3 ounces, machined from heat-treated stainless with wrench flats, in Ionbond matte black or stainless in-the-white. It ships bored for .223; Precision Armament says a qualified gunsmith can open it up to .338 caliber, which matters for anyone building a larger-bore AR-15 on 1/2x28 threads.
