Proof Research has "Cracked The Code" on Carbon fiber wrapped barrels. Their patented process produces barrels that: are much lighter than comparable steel contours, are stiffer and have less harmonic vibration than steel; dissipate heat more quickly than steel resulting in maintained accuracy over longer sessions of fire and longer barrel life. With all these benefits, they are also as accurate as the finest precision steel barrels. They compromise nothing.
