The Super Duty® MOD1-A builds on the proven MOD1 platform by adding fully ambidextrous controls for faster, more intuitive operation in dynamic conditions. Its control layout—shared with Geissele’s GFR and MRGG rifles—supports efficient reloads and malfunction clearance for both left- and right-handed shooters.

The pistol features a left-side magazine release, right-side bolt catch and release, and an instinctive bolt-lock system that improves mechanical flow under pressure. Reliability and accuracy are reinforced by an HPT/MPI-tested Geissele CHF barrel and Forged Stressproof Bolt® made from Carpenter 158+, offering significantly longer service life than mil-spec bolts.

A tuned gas system, Super Compact Gas Block, and Super 42® braided buffer spring reduce recoil while ensuring reliable cycling. Additional highlights include the SSA-E X® two-stage trigger, HUXWRX Flash Hider-QD compatible with FLOW suppressors, and ergonomic components like the MK16 rail, SB Tactical SBA3 brace, and A17 grip with versatile QD sling support.
