Thompson Center Encore Vent Rib Optic Mount Features The Thompson Center Encore Vent Rib Optic Mount attaches directly to the vent rib of the Encore .410 Gauge barrel giving shooters a dedicated factory-matched point to mount a scope or other optic. Because it is purpose built for the vent rib profile it seats flush and square without the gaps or play that a universal clamp-on base can introduce. That solid fit keeps zero consistent between range sessions which matters for a shotgun being used at the longer ranges a scoped turkey load can reach. The aluminum construction keeps the added weight on the barrel to a minimum so the gun still points and carries naturally. Finished in a black matte coating the mount matches the Encore s factory finish and resists the wear of regular field use. Installation is straightforward for anyone comfortable with basic gunsmithing and it requires no permanent alteration to the barrel itself. This mount lets Encore owners add a dedicated scope for turkey hunting or small game work without giving up the barrel s factory sighting options elsewhere in their Encore barrel collection. It is a simple direct way to get a repeatable optic mount onto a Encore vent rib .410 barrel and it is ready for sale at GrabAGun.
