The Maxima Steel Bases are modeled around the popular Weaver design. The low profile of the Maxima Steel Bases give your firearm a sleek look. When used in conjunction with Warne Maxima QD Rings the shooter is able to utilize the open sights by looking over the top of the bases without sacrificing the normal shooting position behind the firearm. Maxima Bases offer a full width recoil slot in each base. This feature allows the recoil control keys of Warne Rings to attain maximum bearing surface. Mounts to receiver with 8-40″ Length Screws.
