Two-Piece 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.
Maxima Bases also offer a full width recoil slot in each base.
