The Monstrum Tactical 1" Diameter Scope Ring Inserts are designed to fit on the inside of 30mm scope rings, allowing for perfect fit mounting of 1" tube scopes with 30mm scope rings. Machined from high quality aerospace aluminum, they are crafted to fit tightly around 1" diameter tube scopes and tightly within 30mm scope rings. The inserts are available in widths of .635 inches (16.15mm) or 1 inch (25.4mm). Please note the inserts have flared edges and will not work with scope rings wider than this.
