A Geissele Super Duty AR-15 Rifle is designed and manufactured to meet a high standard of performance. This rifle features a 14.5” cold hammer forged barrel with a SureFire Closed Tine Warcomp pinned and welded to bring the overall length to 16-inches. The Super Duty already includes all of the performance upgrades that builders love to purchase. Geissele Automatics includes their lower parts kit which includes an ambidextrous safety, Super Duty trigger guard, extended Maritime Bolt Catch, and the two stage SSA-E X Super Semi-Automatic Enhanced trigger. The Reliability Enhanced Bolt Carrier Group with a stress relieved bolt is less susceptible to fatigue and high pressure tested/magnetic particle inspected. Geissele chose their Super 42 buffer spring and combined it with an H2 buffer weight that works with the mid-length gas system to make the Super Duty AR-15 a finely tuned shooter out of the box. The bottom line is that the Geissele Super Duty AR-15 is built using only the best components and engineering to give the user a high performing and extremely reliable rifle.

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.
