Categories: , ,



The Geissele Super Duty AR-15 Rifle was designed with the philosophy that high quality doesn’t mean high cost. This 16” rifle 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 receiver set and assembled with the Geissele Super 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 with Lightning Bow. The 16” barrel is precision machined and cold hammer forged in house and features a heavy profile and mid-length gas system. Combined with the Super 42 buffer spring and H2 buffer weight keep this rifle running reliably and shooting flat. Why build a rifle from the ground up when you can grab this one off the shelf with all the parts you were going to use anyway.

Geissele Automatics manufactures confidence, offering quality triggers and components for the warfighter and competitor. They were established in 2004 with the mission to build the highest quality, reliable triggers for competition and their first trigger, the Hi-Speed National Match trigger, was so popular that they were asked by the Department of Defense to produce a select-fire trigger for the United States Special Operations. Again, it was a success and Geissele decided to bring a semi-automatic version to the civilian market for law enforcement and personal protection.
