Vortex Optics Cantilever Ring Mount with 2" Offset ADR Mount for 30mm Tubes

The ADR cantilever mount is designed for mounting 30mm tubed telescopic sights onto a flattop style AR-15 rifle. The 2-inch offset of this cantilever mount positions the scope in a forward location, allowing the correct eye relief and head placement on an AR-15. This ADR mount will work best with scopes having four inches or less of eye relief. The ADR cantilever ring mount positions the telescopic sight at a height of 1.47 inches from base to center of scope tube.
