Carbine-Length Performance: Specifically tuned with a carbine-length gas system and the “Bomb-proof” Super Gas Block, the MOD1 11.5″ provides a consistent gas pulse and minimized recoil impulse, facilitating rapid follow-up shots.
-
SSA-E with Lightning Bow: Features the Super Semi-Automatic Enhanced (SSA-E) two-stage trigger, providing a crisp break that enhances accuracy while maintaining the safety margins required for duty use.
-
HUXWRX Integration: The system comes standard with the HUXWRX Flash Hider-QD, providing a seamless, duty-ready interface for modern suppression systems.
