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

Verified ownerMitchell Defense is a no-brainer: The quality is impeccable and the customer service is like going back to a time when great service existed and people took pride in their products. I'll be ordering from them again at least one more time before the August 2026 semi-auto "ban" in Colorado.
