The 20-inch 416R stainless steel barrel offers exceptional accuracy and durability. With a 1:8 twist rate, it is optimized for stabilizing a variety of bullet weights, ensuring consistent long-range performance. The rifle-length gas system enhances reliability and reduces recoil, while the .750-inch gas block journal accommodates low-profile gas blocks.
The M4E1-T threaded upper receiver is machined from 7075-T6 aluminum, featuring an integrated handguard mounting platform for increased stability. The paired ATLAS S-ONE handguard provides a slim profile and M-LOK compatibility for mounting accessories. A standard A2 flash hider is installed to reduce muzzle flash.
