Faxon Firearms FFPACOMPSSG02: Consistency is key. Improve your shot with Faxon Firearms\' Exos Pistol Compensators. Faxon Firearms Pistol Compensators have been tested and confirmed compatible with Glock 43X and Glock 48 Pistols. Constructed of 6061 aluminum with a black anodized finish, Faxon Pistol Compensators feature a uniquely angled front port single chamber design, enabling the compensator to improve consistency while reducing muzzle climb and recoil. The angled ports allow gas to deflect upwards as opposed to only deflecting sideways, reducing up and down muzzle movement and improving reliability. Barrel protrusion is designed to fit flush with the slide and has been optimized for Faxon branded barrels. For all other barrels, the barrel should protrude .600 or less for a flush fit. Each compensator comes complete with thread locker, two 6-32 set screws, and a 1/16 Allen wrench.
