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.

The Geissele SMR MK16 is a 15” free float handguard with M-LOK attachment slots for quickly adding lights and grips and features an extremely durable barrel nut attachment system that is also easy to remove. Additional features that come with this rifle is the B5 Systems carbine stock, an A2 pistol grip, and a Geissele Reliability Enhanced Bolt Carrier Group.

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.

Amazing rifle but minor dings.

by -

An amazing rifle right out of the box, although the stock photos on the site are incorrect. It ships with surefire closed warcomp, and the A2 grip is replaced with the geissele grip. The trigger is great as to be expected of geissele, and the work that was put into it was also top notch. Not many companies will stake the castle nut two times.
<br>Only reason the rifle isn't 5 stars is that mine came out of the box with two large and very noticeably nicks to the rifle that are deep. On the upper receiver and hand guard. Other then that rifle is great.
