Just prior to SHOT Show 2017 I met a guy named Aaron. Aaron has used his manufacturing knowledge to start Black Stone Firearms and produce some very impressive match grade barrels that are sleeved in a floating carbon fiber tube.
The carbon fiber tube has vent holes drilled into it to offer rapid heat dissipation. Not only are these barrels sub-moa accurate but they are extremely light and do not heat up nearly as much as a normal AR barrel. They’ve put over 100 rounds through a barrel in a very short time and without letting it cool down are able to grab the barrel and pick the rifle up by it.
These barrels are 416R stainless steel, double stress relieved and hand lapped. They will be retailing starting at $629. Barrel weights are 16″ 25.6oz., 18″ 27.8oz. and 20″ 29.8oz. As usual, my friends at Rainier Arms have secured the initial release of these awesome barrels. Keep an eye out for these to be up on www.RainierArms.com soon.
