Faxon
Faxon EXOS-513 Pistol Compensator for Glock® Gen 3 & FX-19 – 9mm (1/2x28)
Overview
The Faxon EXOS-513 is a platform-focused 9mm pistol compensator engineered for Glock® Gen 3 pistols and the Faxon FX-19 Hellfire. Machined from 6061 aluminum and finished in black anodize, the EXOS-513 uses a single-chamber design with uniquely angled ports to manage propellant gas in a way that reduces muzzle climb and felt recoil while supporting consistent cycling behavior.
Design Highlights
- Angled port geometry redirects gas upward (not only sideways) to reduce up/down muzzle movement.
- Single-chamber compensator design tuned around real pistol timing considerations.
- Flush-fit profile designed to sit cleanly with the slide when paired with Faxon barrels.
- Optimized barrel protrusion guidance: for non-Faxon barrels, a protrusion of 0.600" or less is recommended for a flush fit.

The EXOS-513 is designed and tested specifically for the following models:
- Glock® 19 Gen 3
