Overview
Built for a .308 DPMS-style setup, this 12.5-inch barrel is aimed at compact rifle builds where a shorter profile is part of the intended configuration. It features a government profile, 1:10 twist rate, .750" gas block journal, and 5/8x24 threaded muzzle, giving it a straightforward spec set for compatible assemblies. The QPQ finish and QPQ-coated M4 feed ramp extension are included as listed features, while the product also carries the stated NFA/ATF restrictions that apply to its use and possession. For hunters and shooters planning a legal short-barreled or pistol configuration, it offers a focused barrel option without unnecessary extras.

Considerations & Trade-offs
- The 12.5 inch length is compact, but it also means this barrel is intended for a more specialized setup than a full-length .308 build.
- This is a DPMS-style .308 barrel, so compatibility depends on matching it with the correct platform and receiver configuration.
- The .750 inch gas block journal and 5/8x24 threaded muzzle require matching components; they are not universal fit details.
- NFA/ATF rules apply, and possession/use is restricted depending on the lower receiver configuration, so compliance needs to be verified before purchase.
