The Maxima Aluminum Bases are modeled around the popular we’ver design which is one of the strongest and most versatile mounting systems available today. The low profile of the Maxima Aluminum 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. These 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. – Lightweight Aluminum. – Firearm Specific Fitment. – Designed and MADE IN USA
