Overview

Built for AR-15 builders setting up a 6mm ARC rifle, this barrel line is offered in 18-inch SPR and 20-inch DMR configurations to suit different rifle roles. It is machined from hardened 416R stainless steel and finished with QPQ, with a Nickel Boron coated extended M4 feed ramp extension included in the Premium Series design. The 1:7 twist, rifle-length gas system, and .750 gas block journal provide the core specifications hunters and precision-minded shooters will want to verify against their build. The 20-inch version is threaded 5/8x24, while the shorter option gives a more compact setup without changing the barrel family.

Considerations & Trade-offs

This barrel is offered in two lengths, 18" SPR and 20" DMR, so the fit and handling characteristics will depend on which version is selected.
The 20" DMR configuration is listed at 41.3 oz, which is a meaningful weight consideration for hunters building a lighter rifle.
It uses a rifle-length gas system and a .750" gas block journal, so compatibility should be checked against the intended upper and gas block setup.
The muzzle is threaded 5/8x24, which is useful for accessories but may require attention to local regulations or the specific setup you plan to run.
