Black Hole Weaponry .308 20" Rifle-Length Stainless Steel 1:11 Polygonal Rifled Barrel - DPMS Compatible - Cosmetic-Blem
Black Hole Weaponry Barrels employ the use of 416R, match grade stainless steel. BHW Barrels specialize in Polygonal rifling; The shape of the lands and grooves are based on a circle, so there are no sharp corners or edges for the bullet to conform into. This means there is a tight seal and thus less bullet deformation. This rifling form is unique in its ability to allow the bullet to be centered and fully supported by the barrel’s bore. This arc shaped rifling has long been held in very high regard for its accuracy, increased velocity, reduced gas cutting and ease of cleaning.
***These are genuine Black Hole Weaponry barrels. Another company had paid a deposit to have these barrels made and laser engraved. This company did not follow through on their purchase. We purchased these barrels from Black Hole Weaponry and have removed the other company's logo.

I bought this as a start of a complete build. The barrel perfoms as it should.
It's a good looking set. Blemishes are minimal and won't be a problem. The barrel fits up well with the receiver. Seems quite a bit lighter than the 308 I've used in the past. Im still collecting parts for my build.
