M77-B1 .308 WIN 7.62x51mm NATO caliber. 19.6" in length.
Made from 41v50 material. The handguard retainer slot is cut as well as the extractor clearance on the barrel. The gas port is NOT drilled, but it is spotted for the drilling location to allow the builder to drill the port. Our suggested minimum gas port size is with a #48 (0.076 inch) drill. 14-1lh muzzle threads. Chamber journal is .908". 1-10 twist rate.
Selecting "non-chrome" is the base option for this barrel. The barrel will be raw steel and the builder will need to add the finish coat.
Selecting "chromelined + blued" is our premium option for this barrel. The barrel will come with the bore hard-chrome plated with a blued finish on the exterior.
This item is made in the United States and counts as a 922r compliant part.
