The M10X utilizes almost all metal components (Outside of the polymer pistol grip and stock.) The M10X uses a 4140 milled carbon steel upper receiver where the barrel threads into place. The bolt and bolt carrier are milled from carbon steel on advanced CNC machines.
The M10X lower receiver is stamped from 1.5mm stainless steel for extra strength. To top things off the M10X utilizes an aerospace grade T6 aluminum handguard with a full-length picatinny rail and M-Lok slots for light and optic mounting options out of the box.
