10 inch lapco cut vm-68 barrel in brass. This is a stock vm-68 barrel that has the lapco muzzle break and was likely honed by lapco as well. I have one of these on my vm bullpup and it shoots nice. Barrel is used and inside of muzzle break has a ding that should be sanded out (with fine sand paper). Id=.690, muzzle break id=.710
