Proof Research 16″ 6mm ARC Stainless Steel Barrel Rifle Length Gas System | 128664

Proof Research’s barrels exemplifies relentless pursuit of excellence. Whatever your preference is, you can expect the finest rifle barrel in the industry.The Carbon Fiber barrel features a full-profile, match-grade 416R stainless steel barrel blanks that are made in Proof’s firearms division. The blanks are then turned down to a significantly reduced profile greatly reducing weight. This reduced contour barrel is then wrapped with high-strength, aerospace-grade carbon fiber impregnated with a proprietary matrix resin developed by an advanced composites division, PROOF Research ACD. The carbon fibers have a unique ability to diffuse heat and also moves heat very effectively through the wall of the barrel greatly increasing heat transport. The end result is an aerospace-grade, high-fiber content composite barrel that is stronger, lighter, as accurate as the finest precision steel barrel, and durable to perform in the most demanding environments.
