Geissele Super Duty MOD1-A .300 BLK 8" DDC - Short Barreled Rifle - No Mags

Geissele's Super Duty MOD1-A platform in its 8-inch .300 Blackout SBR configuration — built to the same specifications trusted by elite professionals, in DDC. The Super Duty MOD1-A brings Geissele's cold hammer-forged, chrome-lined barrel, fully ambidextrous MOD1-A controls, and SSA-E X trigger with Lightning Bow to a compact short-barreled format with 9.3" MK16 M-LOK rail and B5 SOPMOD stock. The HUXWRX Flash Hider-QD 762 provides suppressor-compatible interface for seamless transitions to HUXWRX FLOW-series suppressors.

The Geissele Super Duty MOD1-A is a .300 Blackout short-barreled rifle featuring a 8-inch cold hammer-forged chrome-lined barrel with 1:7 twist, Super Compact gas block and tuned gas system, SSA-E X trigger with Lightning Bow, fully ambidextrous MOD1-A controls, and a DDC finish. 5/8x24 threaded muzzle. HUXWRX Flash Hider-QD 762. Super Configurable Safety Selector.

Four features define the Super Duty MOD1-A's performance advantage. The cold hammer-forged, chrome-lined barrel — HPT and MPI tested — provides dimensional consistency and service life that exceeds standard button-rifled alternatives, and the chrome lining resists fouling and corrosion through the sustained fire schedules that duty and professional use generates. Fully ambidextrous MOD1-A controls include a left-side magazine release below the Maritime Bolt Catch, right-side bolt catch and release buttons below the ejection port, and a dust-cover-actuated bolt catch lock — a system that enhances speed and consistency on both sides rather than merely accommodating the non-dominant hand. The SSA-E X trigger with Lightning Bow provides the crisp, predictable break that precision work demands with a wide Lightning Bow for positive trigger control through gloves and under stress. Super Compact gas block and tuned gas system ensures reliable cycling suppressed or unsuppressed, with supersonic and subsonic ammunition, without requiring user adjustment.
