Vortex Precision Extended Cantilever Mount

The 20 MOA cant is specifically designed for long-range shooting. It angles your scope downward, which effectively adds 20 minutes of angle to your elevation adjustment range, allowing you to dial in shots at significantly longer distances without running out of internal scope adjustment.

The cantilever design pushes the optic forward, which is essential for platforms like the AR-15. It allows you to achieve proper eye relief and a comfortable head position without needing to mount the scope awkwardly far back on the receiver.

No, this specific model is designed exclusively for scopes with a 34 mm main tube diameter. Always verify your optic's tube size before purchasing to ensure a proper fit.

To ensure stability without damaging your optic or rail, tighten the ring screws to 15-18 in/lbs and the base screws to 45-50 in/lbs. Using a torque wrench is highly recommended to stay within these ranges.

The VIP Lifetime Warranty covers the mount against defects in materials and workmanship for the lifetime of the product. If it fails or breaks, Vortex will repair or replace it at no charge, regardless of how it happened.

This height is generally considered a 'lower 1/3' or 'absolute co-witness' height depending on your specific optic and rifle setup. It is designed to provide a comfortable cheek weld for most shooters using modern sporting rifles.
