SureFire Muzzle Brake For Barrett M107 SureFire SFMB muzzle brake suppressor adapters greatly reduce both recoil impulse and muzzle rise so that your weapon tracks straight back, keeping you on target for faster shot-to-shot recovery. Our proprietary Impulse Diffusion design minimizes side blast and rear-directed concussion effects.

The SFMB design incorporates multiple bearing surfaces to ensure superior suppressor alignment. Blind pilot holes at the 3o clock and 9o clock positions enable fine-tuning of recoil characteristics for individual shooting styles or ammunition characteristics. Blind pilot holes at the 6o clock position enable indexing the adapter at bottom dead center. All thats required is a basic hand drill and appropriate drill bits.
