Geissele Automatics Super Duty MOD1-A 5.56 AR-15 SBR - 14.5"

Geissele's Super Duty MOD1-A platform in its 14.5-inch 5.56 NATO SBR configuration — built to the same specifications trusted by elite professionals, in black. The Super Duty MOD1-A brings Geissele's cold hammer-forged, chrome-lined barrel, fully ambidextrous MOD1-A controls, and SSA-X two-stage trigger to a compact short-barreled format with telescoping AR-style stock.

The Geissele Super Duty MOD1-A is a 5.56 NATO short-barreled rifle featuring a 14.5-inch cold hammer-forged chrome-lined barrel with 1:7 twist, Super Compact gas system, SSA-X two-stage trigger, fully ambidextrous MOD1-A controls, and a black finish. 1/2x28 threaded muzzle. Integrated Picatinny optics rail. Ambidextrous 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-X two-stage trigger 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 system ensures reliable cycling suppressed or unsuppressed, with supersonic and subsonic ammunition, without requiring user adjustment.

Compatible with standard AR-15 STANAG magazines. 14.5-inch barrel, 1:7 twist. Overall length: 33–34 inches. Weight: approximately 7.0 lbs.
