The Geissele Super Duty MOD1 11.5" Desert Dirt Color SBR brings professional, duty-grade engineering to an ultra-maneuverable and compact short-barreled platform. At its core, the rifle features a 11.5-inch cold hammer-forged, chrome-lined barrel with a tapered profile optimized for exceptional balance and sustained accuracy under high round counts. This premium NFA-regulated weapon operates via a finely tuned direct impingement system and houses a Nanoweapon-coated Reliability Enhanced Bolt Carrier Group paired with a forged Carpenter 158+ Stressproof Bolt. Shooters benefit from the ultra-smooth, crisp break of the factory-installed Geissele SSA-E X two-stage trigger with an ergonomic Lightning Bow design. Outfitted with a 10.5-inch MK16 Super Modular rail, a B5 Systems Enhanced SOPMOD stock, and an effective Surefire SOCOM closed-tine muzzle device, this hard-use platform delivers peak modularity and recoil management.
