Kgm A-QD-FH-S-1 Quick Detach Flash Hider | 1/2×28

The Kgm Technologies A-QD-FH-S-1 is a quick-detach flash hider designed to interface with compatible R-series suppressors on barrels that use 1/2×28 muzzle threads. It uses a birdcage-style front and a taper mounting surface to stabilize the suppressor, and includes a ratcheting secondary retention system for repeatable alignment. Construction uses heat-treated Chromoly steel finished with an OXyN gas nitride process for wear resistance and corrosion protection.

Typical applications include range use with suppressors and precision/target shooting where fast, repeatable muzzle-device attachment is desired. It is also suitable for competition platforms that require quick suppressor changes between stages.
