Vortex® Standard Duty 2" Offset Cantilever Ring Mount

Vortex® Cantilever Riflescope 30mm Ring Mount lets you equip and properly use a riflescope on your AR-15 flat top rifle. Featuring a 2 to 3" offset orientation, it allows you to install your telescopic sight in a forward location. With its offset position, you can maintain the correct head placement and eye relief when looking through the riflescope, impossible on the AR-15 with a straight mount.
