The Geissele Super Duty AR-15 Pistol was designed with the philosophy that high quality doesn’t mean high cost. This 10.3” pistol chambered in 5.56 NATO is built to the standards that you come to expect from Geissele Automatics with all the popular features that you love. It is built on a Mil-Spec 7075-T6 aluminum receiver set and assembled with the Geissele Ultra Duty lower parts kit that includes the ambidextrous Posi-snap safety selector, Super Duty trigger guard, Maritime Extended bolt catch, and the SSA-E X Super Semi-Automatic Enhanced trigger. The 10.3” barrel is precision machined and button rifled in house and features chrome lining and a carbine length gas system. Combined with the Super 42 buffer spring and H2 buffer weight keep this pistol running reliably and shooting flat. Why build an AR pistol from the ground up when you can grab this one off the shelf with all the parts you were going to use anyway.
