Our rifles aren’t just built — they’re engineered to outlast and outperform.

null

Thermal Fit Barrels

We heat the billet upper to a precise temperature so the barrel extension thermally locks into the receiver as it cools. That interference fit turns the barrel and upper into a single rigid assembly, cutting barrel shift and improving harmonics. The result: bolt-rifle-level accuracy and a more consistent point of impact under sustained fire and after maintenance.

null

Frictionless Upper Receiver

Our 7075-T6 billet uppers are machined and precision-ground to ultra-tight tolerances, then matched to an ArmorLube-coated BCG. That combination dramatically reduces internal friction and carbon hang-ups, producing smoother bolt velocity, less wear on contact surfaces, and more consistent cycling — especially during high-round-count use.

null

Proprietary Flat-Wire Buffer Spring

Our cryo-treated flat-wire buffer spring and matched buffer increase forward pressure and resist fatigue far longer than conventional round wire. Tested well past industry norms, it eliminates the spring “twang,” evens out recoil impulse, and preserves consistent lockup and ejection over hundreds of thousands of cycles — a cornerstone of long-term reliability.

Good people. Had some questions because I'm new to this kind of gun, and they took the time to explain things and make recommendations for accessories. If what you want isn't in stock, just keep checking, it'll probably be back in a day or 2. I saw my gun go in and out of stock a dozen times before I was finally ready to pull the trigger. Then it was out of stock. But it came back in the next day.

Good Company, shipped fast, and Customer Service actually ANSWERS THE PHONE! I had a question before I ordered, spoke to some guy named Nathan. He helped me out, but could use more training. This is a good American Company that makes Great rifles.

We met the owner of Mitchell Defense at SHOT Show last year. The guy is truly passionate about the gun industry and giving back. After several conversations, I believe he genuinely cares about making our industry better and furthering our future. Totally inline with Team 144 values. 10/10! -Ryan Fraker , Team 144
