Ideal for a gunsmith or builder with access to a lathe. This caliber blank has been skimmed down the full length of the barrel to 15/16" diameter and trued to the bore. We then faced, chamfered, and chambered the opposite end of the barrel for a 7.62x39mm, and 5.56 NATO caliber round. The outside journal of the chamber end has also been turned to 0.9200"-0.9210" so that the builder can machine the trunnion journal to fit. The remainder of the barrel is ready to be cut to length, muzzle crowned and/or threaded, and turned down to the desired size for your build/kit by anyone with a lathe, knowledge, and capabilities of doing so. No milling has been added to this blank. Land is .300"-.302", groove is .310"-.312". 1 in 10 twist for the 7.62x39. The 5.56 blanks are 1 in 9 twist.
- This barrel does NOT have a muzzle crown.
- No milling has been added on the chamber or anywhere else on the blank.
