Vortex Optics Cantilever 30mm Riflescope Ring for StrikeFire

The Vortex Optics 30mm Riflescope Ring provides extra rail room for rear Back Up Iron Sights (BUIS) when using the StrikeFire red dot along with the VMX-3T magnifier. The cantilever ring will move the StrikeFire forward about one inch. This Ring provides absolute lower 1/3 co-witness mounting height and will work with most 30mm red dot sights.
