Geissele® Super Duty 5.56 NATO/.223 Rem. Semi-automatic AR-15 Pistol
Calling the Geissele Super Duty an AR-15 Pistol feels like a bit of an…understatement. It's "just" an AR in the same way that the Ford GT is "just" a car. Nearly every single component has been upgraded compared to mil-spec—and the result is one of the smoothest-shooting, most accurate pistols to ever wear the AR badge.
It starts with the Super Duty upper and lower receivers, each precision machined from 7075-T6 aluminum. The lower features Geissele's Ultra Duty Lower Parts Kit with the Ambidextrous Super Configurable Safety and Ultra Precision trigger guard. The SSA-X trigger with Lightning Bow is a nano-coated, 2-stage trigger featuring a wide body and bow shape that strikes the perfect balance between a classic M4 trigger and a flat-body trigger.
The heart of the Pistol is the REBCG (Reliability Enhanced Bolt Carrier Group). This nano-coated BCG is machined from mil-spec 8620 steel, with a properly torqued and staked, chrome-lined gas key. The cam pin is machined from advanced, medical steel known as H13, which is also nano-coated for maximum corrosion and wear resistance. The REBCG also features extended upper rails, providing greater stability and dramatically increasing feeding reliability.
The REBCG comes with the Geissele Stressproof Bolt, which is forged from barstock, not machined, yielding a bolt capable of 5 times the life of a mil-spec bolt. Each bolt is rigorously inspected, high pressure tested, mag particle inspected and nano-coated.
For accuracy, the Super Duty features an 10.3" manganese phosphate-coated, chrome-lined barrel that comes topped with a Surefire Closed-Tine Warcomp muzzle device to help control flash and mitigate some recoil.
Rounding up the package is a 9.3” MK16 Super Modular Rail that mates to upper receiver via a center aligning tab that removes any chance of rail rotation. The MK16 family of rails are renowned by operators for their performance and comfort. If you want the best, look no further.
