Geissele Super Duty MOD1-A 5.56 NATO AR Pistol - 11.5" - Black - No Mags

The Geissele Super Duty MOD1-A pistol brings the full ambidextrous Super Duty component ecosystem to a 11.5-inch 5.56 NATO AR pistol configuration — the same Stressproof bolt, SSA-E X trigger, CHF chrome-lined barrel, and HUXWRX QD muzzle device as the rifle variants, in a compact platform with SB Tactical SBA3 brace, in black.

The Geissele Super Duty MOD1-A is a semi-automatic 5.56 NATO AR pistol built on a Super Duty ambidextrous billet lower receiver and Super Duty M4 upper receiver, featuring a 11.5-inch cold hammer forged, chrome-lined barrel at 1:7 twist, an 10.5" MK16 rail with Geissele center tab, factory-installed fully ambidextrous controls, and an SB Tactical SBA3 pistol brace. Color: Black.

The MOD1-A pistol compresses the Super Duty MOD1-A's full-capability component specification into a shorter, more maneuverable configuration while retaining every core performance element. The 11.5-inch CHF chrome-lined barrel maintains the 1:7 twist and Geissele tapered profile of the longer rifle variants, with the gas port size (.067") tuned specifically for the shorter Carbine gas length to maintain reliable cycling and consistent bolt carrier velocity at the shorter dwell time. The same ambidextrous control layout runs throughout: left-side magazine release below the Maritime Bolt Catch, right-side bolt catch and release buttons below the ejection port — the integrated layout from Geissele's GFR and MRGG professional rifles. The Forged Stressproof Bolt from Carpenter 158+ steel — HPT and MPI certified — is rated for five times the service life of a mil-spec bolt and pairs with the Reliability Enhanced BCG for the same dependability standard as the full-length variants. The Super 42 braided buffer spring with H3 buffer manages the increased bolt carrier velocity of the shorter gas dwell, and the SSA-E X two-stage trigger with Lightning Bow and Nanoweapon-coated internals delivers the same crisp, predictable break as the rifle variants. The HUXWRX Flash Hider-QD at 1/2x28 provides full HUXWRX FLOW suppressor compatibility — particularly relevant in a short-barrel configuration where suppressor use most significantly affects the shooter's environment. The SB Tactical SBA3 brace completes the pistol-legal build.
