Proof Research PR15 Carbon Fiber 18″ 5.56
Our patented manufacturing process begins with full-profile, match-grade 416R stainless steel barrel blanks that are made in our firearms division. These 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 our advanced composites division, Proof Research ACD.
Because our rifle barrels are engineered for thermal performance, they also move heat very effectively through the wall (thickness) of the barrel, greatly increasing heat transport and resulting in barrels that cool faster and maintain accuracy over longer sessions of fire. 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 maintains its accuracy in the most demanding environments.
- Up to 64% lighter than traditional steel barrels of similar contour.
- Match-grade accuracy.
- Improved heat dissipation for cooler and longer lasting barrels.
- No point-of-impact shift during high-volume fire.
- Reduced harmonic barrel vibration.
- Unprecedented durability.
