Bellows, 5/8-24 Plan B 17-4 SS Radial Brake
Engineered Displacement.
Machined from premium, American-sourced 17-4 PH Stainless Steel, the Bellows Series Radial Brake is built for extreme durability under harsh, high-heat use. Utilizes precision-drilled 0.0625" diameter ports to displace, compress, and redirect explosive blast gases, reducing muzzle rise and recoil.
Engraved with the ISA logo on the side, the Bellows Series features a seamless Plan B compatible taper mount design with a .308 cal bore, making it also compatible with .308 and smaller calibers. It delivers maximum recoil management and structural integrity whether run as a standalone muzzle device or as a rock-solid suppressor host.
