BOSS End Cap Features The Boss Suppressors End Cap is machined from stainless steel to withstand the repeated thermal and pressure stress that builds up inside a suppressor during sustained firing. Its brake style design helps direct gas flow at the muzzle end which can aid in controlling concussion and felt recoil on supported 1.5 inch Boss suppressor models. The black finish matches factory Boss suppressor coloring so the end cap blends in rather than standing out on a completed build. Compatibility is limited to 1.5 inch diameter Boss suppressor housings making fitment straightforward for owners of that specific line. Because this is a direct factory-style replacement part installation follows the same process as the original end cap it replaces requiring no modification to the suppressor body. Stainless steel was chosen for its corrosion resistance which matters given the exposure to carbon fouling and moisture that suppressor internals see over time. Owners running a 7.62 or .30 caliber host rifle through a compatible Boss suppressor gain a durable way to keep their can performing as intended. This end cap is a practical maintenance and upgrade component for sale at GrabAGun.
