The Faxon Firearms EXOS-515 Compensator (brand part no. FF-P-A-COMP-DS-S-01) is built for the SIG P320 in 9mm with a 1/2×28 thread and an overall length of about 1.40 inches. Machined from 6061 aluminum with a black anodized finish, it uses Faxon’s uniquely angled front-port, single-chamber design to deflect gas upward instead of only sideways, reducing muzzle climb and recoil while improving reliability over flat side-venting compensators. Barrel protrusion is optimized for Faxon-branded barrels for a flush fit; with other barrels, protrusion should be .600 inches or less for the same flush result. Each compensator ships complete with thread locker, two 6-32 set screws, and a 1/16-inch Allen wrench.
