I’ve had this in my safe new and unused I paid $331.00 (YOURS FOR $199). The Lightweight THM Tension Barrel sets the standard for what a lightweight barrel should be. It features a sleeve that is used to create tension on the barrel itself. This unique design eliminates issues typically found in smaller barrel profiles. The THM tension barrel consists of a special taper honed match barrel and chamber. This is the ultimate lightweight barrel. All barrels fit for the 10/22 LR are drilled and tapped to accept Volquartsen Barrel Mounted Scope Mount. This Model has the premium carbon fiber sleeve. This barrel can be set up with 1/2×28 threads and fitted with any of Volquartsen available compensators.
