Vortex Precision Quick-Release 1-Piece Extended Cantilever Mount Picatinny-Style 30mm Rings

This quick release cantilever mount is designed for mounting telescopic sights with scopes that have a 30mm tube onto a flattop style AR-15 rifle. When used on an AR-15, the 2" offset of this cantilever mount positions the scope in a forward position, providing correct eye relief and head placement. The quick release 30mm one-piece rings are precision machined from 6061 T6 aluminum for extreme toughness, yet make them extremely light.
