Volquartsen Carbon Fiber 10/22 Tension BarrelsThreaded Tension Tuned Match Grade Barrels w/Optional Muzzle Brake The Volquartsen approach to making a lighter weight barrel for the Ruger 10/22 is unique... They use a tensioning system to enhance the accuracy and cooling characteristics. The stainless steel core of these barrels is referred to as "THM" for Taper Honed Match barrel and chamber. The bore and chamber dimensions vary no more than .0001" from breech to muzzle... That's 1/10,000th of an inch. "Taper Honed" refers to the polish of the bore and the improved transition from the chamber to the bore. Dimensions are confirmed by digital measurements. Length: 16.5", Weight: 1lb. 4oz. The "core" of these barrels is a small diameter match grade barrel. Now, as diameters get smaller, the potential for vibration increases. So, Volquartsen reduces vibration by TENSIONING the core within a light weight carbon fiber sleeve. The result is a lighter barrel with the same stiffness and vibration deadening as a heavy match barrel... Quite a unique system. Our Volquartsen Carbon Fiber 10/22 Tension barrels are available in two configurations: Threaded 1/2x28, OR Threaded 1/2x28 with the Volquartsen Stainless Forward Blow Compensator (FBC Brake).
