Quickly bring your scope to new heights by mounting it with a Vortex® Precision Extended Cantilever Scope Mount. This rock-solid mount is machined from a block of 6061 T6 aluminum and finished in hard coat Type 3 anodized finish. The extended design will position your scope in a forward location and maintain your proper head position and eye relief on an AR-15 platform. A 20 MOA cant is incorporated to allow you to zero in at greater distances. Lightweight construction helps maintain the accuracy of your rifle.
