The Volquartsen Lightweight Carbon Fiber Barrel sets the standard for a lightweight barrel - bull barrel match accuracy at half the weight! A stainless steel barrel fitted with a woven carbon fiber tube creates an air space between the barrel and sleeve, helping the barrel stay cool under rapid-fire conditions. The rigidity of the carbon fiber tube allows us to put the barrel in tension, minimizing barrel vibrations typically found on smaller barrel diameters. Summit barrels feature a machined ramp making for a smooth transition from magazine to chamber when cycling the straight-pull action.
