Black Hole Weaponry 308 Barrel 18″ Rifle Length Gas System Standard Black - Picture is of a Mid Length gas System Barrel

We use 416R stainless steel and our rifling shape is a series of arcs instead of square corners, as in the traditional style of Enfield rifling. This arc shaped rifling has long been held in very high regard for its accuracy, increased velocity, reduced gas cutting and ease of cleaning. Here you can see the difference between classic Enfield rifling compared to the 5 land and 3 land polygonal rifling.
