Forward Controls Design - Brake, sound suppressor mount with 0.900 x 24 external threads, 5/8x24

The Forward Controls Design 1210RF is a single-chamber muzzle brake designed for compatible .30-caliber rifles with 5/8x24 muzzle threads and suppressor systems using a 0.900x24 Plan B-style interface. Its external 0.900x24 threads and taper provide compatibility with Plan B-type suppressor mounts and adapters such as the Rearden Atlas, giving the brake dual-purpose use as both a recoil-reducing muzzle device and suppressor mount. Machined from 17-4 PH stainless steel, the 1210RF measures approximately 1.725 inches long, weighs about 2.17 oz., and uses 3/4-inch wrench flats for installation. The single-chamber brake design helps reduce felt recoil while also acting as a sacrificial first baffle when used with a compatible suppressor. For shooters building around a 5/8x24 rifle and the Plan B/Rearden mounting ecosystem, the FCD 1210RF provides a compact combination of recoil control and suppressor-mount compatibility.
