Proof Research Carbon Fiber Barrels Are up to 64% Lighter than Traditional Barrels of the Same Contour

Proof Research produces barrels which are made to the very highest quality standards. The design and manufacturing processes which are used are state-of-the-art and go above and beyond. Each barrel produced will exemplify their founders' relentless pursuit of excellence. The ultimate goal of Proof Research is to provide you with the performance and quality you have been missing whether it's to shoot your best groups, compete at the highest levels, or bag that elusive animal. Whatever your choice of shooting discipline, Proof Research has the finest barrels in the firearms industry.

If you demand the most innovative technologies from your equipment, Proof Research's Carbon Fiber barrels are just what you need. Instead of a full steel design, these barrels begin as match-grade 416R stainless steel barrel blanks. These blanks are then turned down to a significantly reduced profile to greatly reduce weight. This reduced contour barrel is then wrapped with high-strength, aerospace-grade carbon fiber impregnated with a proprietary matrix resin. With this unique hybrid construction, you get a barrel which cools faster, maintains accuracy over longer firing sessions, and most importantly is up to 64% lighters than comparable steel barrels!
