Maxima Steel Bases are precision CNC machined from solid steel and are held to very tight tolerances. The Maxima Steel Base design is modeled around the popular Weaver design, which is one of the strongest and most versatile mounting systems available today. The low profile of the Maxima Steel Bases give your firearm a sleek, good 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 also offer a full width recoil slot in each base. This feature allows the recoil control keys of Warne Rings to attain maximum bearing surface, stathing off severe recoil..
