Agency Arms 417 Single Port Compensator for Glock Gen4 – Black

The Agency Arms 417 Single Port Compensator reduces muzzle rise and speeds up follow-up shots on Glock Gen4 pistols. The single vertical port vents gas upward to counteract recoil, keeping the sight picture flatter during rapid fire. This comp is engineered for competitive shooters and tactical applications where split times matter.

Machined from steel with a black finish, the 417 installs on factory Glock Gen4 threaded barrels using standard 1/2x28 threads. The single-port design maintains a lower profile than multi-port comps while still delivering measurable recoil reduction. No permanent modifications required—simply thread onto your barrel and secure with the included set screw. Compatible with most Glock Gen4 models that accept threaded barrels (excluding subcompacts). Verify your barrel thread pitch before ordering.
