AR-10 .308 18" Fluted Stainless Barrel, 416 Stainless, 1:10 Twist, Mid-Length Gas

This AR-10 18" Fluted Barrel in .308 Winchester is precision-machined from 416 stainless steel, hardened to 26–32 RC, and stress-relieved for exceptional durability and accuracy.

Chambered in .308 Win with a 1:10 twist rate, this barrel provides excellent stabilization for a wide range of bullet weights, making it ideal for precision shooting or long-range engagements. The mid-length gas system and .750 gas block journal deliver smooth cycling and optimal performance on your DPMS-pattern AR-10 build.

Includes barrel extension with M4 feed ramps and pre-drilled gas port. Threaded 5/8x24 for standard muzzle devices or suppressor mounts.
