The Talley HC740735 is unique in that it features a one-piece construction. This rigid design ensures there is no joint between the scope and the rifle. This unitized style of the Talley Lightweight Alloy Scope Mount prevents the possibility of a loose connection or an out of alignment interface which is often the issue with traditional two-piece designs. The added strength and durability this mount provides puts it at an advantage over competing steel rings and bases while maintaining a lighter overall weight. The mount starts as an extrusion of the 7000 series alloy that\'s known for its durability. It is then precision CNC-machined to its final design. This process gives us the strongest yet lightest mount system available in the market.
