Faxon EXOS-523 Pistol Compensator for Glock® 43 – 9mm (1/2x28)

Overview

The Faxon EXOS-523 pistol compensator is engineered and tested for the Glock® 43 platform to improve shooting consistency through controlled gas redirection. Machined from 6061 aluminum and finished in black anodize, the EXOS-523 uses a single-chamber design with uniquely angled ports to help reduce muzzle climb and manage felt recoil while supporting stable cycling characteristics across properly configured hosts.

• Single-chamber compensator design built around real-world pistol operating dynamics
• Flush-fit profile optimized for Faxon branded barrels
• For non-Faxon barrels, a protrusion of 0.600 inch or less is recommended for a flush fit
