BOSS Caliber End Cap Features The BOSS Suppressors Caliber End Cap is built specifically to fit 1.75 diameter BOSS suppressor models replacing a worn or damaged factory end cap with a direct-fit component. Machined in .338 caliber it maintains the correct bore clearance the suppressor was designed around which matters for preserving accuracy and the suppressor s sound and flash performance. Constructed from stainless steel the end cap resists the corrosion and heat cycling that suppressor components are regularly exposed to during use. Its finish is black keeping the appearance consistent with the rest of a blacked-out suppressor build. Because this end cap is model and caliber specific it is intended only for 1.75 BOSS suppressor models chambered for .338 caliber rounds so fitment should be confirmed before ordering. Keeping a spare or replacement end cap on hand lets a suppressor owner swap out a damaged component without sending the entire unit back for service. The stainless steel construction is chosen for its durability under repeated firing cycles standing up to the wear that a suppressor s end components see over time. The BOSS Suppressors Caliber End Cap is available for sale at GrabAGun for owners looking to maintain or repair their 1.75 BOSS suppressor.
