Black Hole Weaponry.308 18" Mid-Length Stainless Steel 1:11 Polygonal Rifled Barrel - DPMS Compatible
Blackhole 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.
**THIS BARREL COMES WITH A FREE 5.56 AR-15 STRIPPED UPPER. THE STRIPPED UPPER IS NOT COMPATIBLE WITH THE .308 BARREL.

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.
