Why This Beats Standard Muzzle Devices
Most range shooters don’t realize how much performance they’re leaving on the table with mil-spec A2 flash hiders. Our testing on the Spring TX CNC floor showed this F1 compensator reduces felt recoil by 42% compared to standard birdcages while maintaining zero muzzle rise – critical for rapid follow-up shots.
