Thompson Center Encore Cross-Slot Base Features The Thompson Center Arms Encore Cross-Slot Base is a one-piece aluminum scope mount finished in matte black designed to work with Cross-Slot style scope rings. It mounts directly to the factory-drilled holes already present in the barrel eliminating the need for any additional drilling or tapping work. This direct-fit design makes it one of the simplest ways to add glass to a Thompson Center rifle platform. Tightening the mounting screws to 25 in-lbs ensures a secure properly torqued installation that will not loosen under recoil. Built to fit the Encore Triumph Omega and Impact platforms this base offers broad compatibility across Thompson Center s single-shot rifle lineup. The matte black aluminum construction matches the factory finish of most Encore-series firearms while standing up to the elements during hunting season. Because it uses the Cross-Slot ring system it pairs easily with a wide range of compatible rings for mounting various scope tube diameters. The Thompson Center Arms Encore Cross-Slot Base is available for sale at GrabAGun for shooters looking to add a scope to their Encore-platform rifle.
