The most advanced muzzle brake available
Proprietary Impulse Diffusion design minimizes side and rear blast
Reign Over Recoil. 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. Precision machined from U.S. mill-certified heat-treated stainless steel bar stock and DLC-coated for extreme durability, they are available for a variety of weapon calibers and muzzle thread specs, and every SFMB serves as a rock-solid mounting adapter for SureFire’s combat-proven SOCOM Series Fast-Attach® suppressors. The SFMB design incorporates multiple bearing surfaces to ensure superior suppressor alignment. Blind pilot holes at the 3 o’ clock and 9 o’clock positions enable fine-tuning of recoil characteristics for individual shooting styles or ammunition characteristics. Blind pilot holes at the 6 o’clock position enable indexing the adapter at bottom dead center. All that’s required is a basic hand drill and appropriate drill bits.

The KAC URX 4 Rail is a fully modular design that utilizes the revolutionary KeyMod accessory mounting system. The URX 4 Rail is stronger and more stable than previous URX designs due to its one piece construction. It is also lighter due to its Integral Barrel Nut (IBN) system of attachment. The IBN system allows the rail itself to act as the barrel nut when torqued onto the rifle, completely eliminating the need for a separate steel barrel nut. KeyMod accessories may be mounted anywhere along the URX 4s length, making it one of the most user configurable designs on the market. The URX 4 includes two QD sling swivel sockets, one on the left side and one on the right.
