BOSS End Cap Features The Boss Suppressors End Cap is machined from stainless steel and finished in black to match factory Boss silencer builds. It is sized for 1.5-inch diameter Boss suppressor models bored to .30 caliber so it threads in without modification on compatible hosts. The standard non-vented configuration keeps the suppressor s baffle stack sealed for consistent sound and gas control. This makes it a straightforward replacement part for an owner servicing their suppressor. Having a factory matched stainless end cap on hand keeps a Boss 1.5-inch suppressor in service rather than sidelined for repair. The black finish keeps the component s appearance consistent with the rest of the suppressor body. Because it is built to Boss Suppressors own 1.5-inch model specifications fitment is direct rather than requiring adaptation. It is available for sale at GrabAGun for shooters maintaining their Boss .30 caliber silencer.
