My favorite bases - Burris Trumount Universal Rifle Scope Two Piece Base

Perfect fit to receiver. Visually pleasing as well. Solid construction. With the reversible rear (windage adjustable), in either direction, unlike virtually all other bases, this one clears the breech completely offering a clean, pleasant aesthetic. Fit to ring on the dovetail side is too tight (which was in the past, NOT the case) - this includes Burris Signature rings which, you would think, would be a perfect fit. Still, I give these a top rating!
