Description
SureFire 556-1/2-28 Muzzle Brake/Suppressor Adapter, fits M4 / M16 weapons and variants with 1/2-28 muzzle threads and SureFire SOCOM Series
SureFire 556-1/2-28 muzzle brake, greatly reduces both recoil impulse and muzzle rise so that the weapon tracks straight back to keep you on target for faster shot-to-shot recovery, while its patented Impulse Diffusion design minimizes side blast and rear-directed concussion effects and also serves as a rock-solid mounting adapter for the SOCOM Series 5.56 mm Fast-Attach suppressors. Precision machined from US mill-certified heat-treated stainless steel bar stock including high-precision single-point cut threads for optimum thread interface the 556-1/2-28 muzzle brake is given a black Ionbond DLC coating to provide maximum protection under harsh environmental conditions and to facilitate cleaning even after extreme use.
All SureFire SOCOM Series muzzle brakes have blind pilot holes at the 3 and 9 o’clock position to enable fine-tuning of recoil characteristics for individual shooting styles or ammunition characteristics. They also have blind pilot holes at the 6 o’clock position to enable indexing the adapter at bottom dead center, and to pin-and-weld on short-barreled rifles. All that is required is a basic hand drill and appropriate drill bits.
