Talley's Lightweight Scope Mount features a unique, one-piece construction extruded from 7000 series alloy and precision CNC-machined to its final design. It has no joint between the scope and the rifle which ultimately provides more strength and durability than most steel rings and bases, but with a lighter overall weight. This model is compatible with Winchester M70 rifles and has 30mm rings with a medium mount height and a matte black finish.
