Black Hole Weaponry AR-15 Pistol 10" HBAR Stainless Steel 1:8.5 Polygonal Rifled Barrel - 300 Blackout Chamber
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.

I have taken 3 deer with this barrel. Two from over 138 yards on the run with one bullet each, center mass.
I shoot 120/125 grain Barnes TSX Black tips.
On another occasion using my Burris Eliminator I scope. I ranged in a shot at 412 yards with 120 grain Barnes Black Tip Again on a Handload with Long Shot Powder. I missed my point of aim by 8" to the right (me not compensating for a left to right wind about 20 mph) and 6" high. If that was another deer that would have been a kill shot too.
I am having trouble finding ammo that shoots accurate. Have tried 8 leading brand's and can only get a 2 inch group at 50 yds off sled. Barrel should shoot much better
