The Geissele Super Duty AR-15 Rifle was designed with the philosophy that high quality doesn’t mean high cost. This 14.5” 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. The 14.5” barrel is cold hammer forged, precision machined, 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 13.5” 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 the Reliability Enhanced Bolt Carrier Group with a stress relieved bolt and improved geometry for a better functioning rifle.

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.

Built for duty, and worth every penny.

Not even a geissele fan boy, but very impressed. I bought this rifle because I needed a quality gun for work. Quality inside and out. I'm getting about one and a quarter to one and a half minute accuracy with M855. The trigger is amazing, the bolt cycles super smooth, and the recoil impulse is really impressive. Added a surefire Mini-Socom2, with no gas issues. And to top it off, the gun is pretty light weight. I would highly recommend it for any law enforcement officer having to buy their own carbine. This thing is built to last you till retirement. It really makes you look at the old Colt 6920's and Bushmaster equivalents like they were from the stone age.

Just got this a few weeks ago and while I initially did not want to spend this much for a HD / SHTF gun, after shooting it, it is worth every penny!
<br>Running EOTech on it and blasting away with experience ammo because it's too fun to shoot. Will be adding a Surefire Socom which will make the shooters next to me happy!
<br>10/10 Would buy again

Excellent carbine


I’ve had this rifle for 1month and taken it to the range twice. Paired it with a PA GLx 2x prism. It has run flawlessly thus far. From 10 to 300 yards, it feels like a rifle designed for real world use. My only complaint (albeit a very small one) is the pistol grip. I like one that is more vertical.
<br>Overall, great rifle that is lightweight, ergonomic and built right. Buy it with confidence.
