Welcome to the forum.I have used the Burris standard,signature rings, on most of my guns.They are interchancable with the Leupols standard bases and vice-versa.Ihere are two advantages to the burris Signature rings,ie they have 4 screw rings and they have plastic inserts and offset inserts that allow you to move the point of impact without using the internal scope adjustments and,no ring marks are left on the scope tube.
