On Barrel types that use an extension such as the AR 308 platform rifles, we manufacture our own in house extensions machined from hardened material offering strength, dimensional stability and are held to .001” in critical areas ensuring that the locking lugs are perpendicular to the bore, class 3 threads. These extensions are stronger, safer, and more accurate than possible with any conventional post machining heat treated extension. Available in 30 caliber and sub 30 caliber feed ramps.
