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.

  1. great barrel 5 Star Review

    Posted by on 11th Apr 2014

    I bought this to go on a jd tech set very happy with it. Great finish and fit cleans easier than a standard rifled barrel. Will buy more for my next build

  2. Nice barrel, shoots good 5 Star Review

    Posted by on 21st Feb 2014

    I put this barrel on a Matrix Aerospace AR-10A upper and lower rec set with a DPMS style Nickel Boron BCG and shot under 1 MOA after break in (.675-.910 moa) Barrel comes clean very easy and looks like a mirror after 3 boresnakes and some Blue Wonder.

    Almost one ragged hole with 168 gr AMAx and starting load of Varget.
