ADR-X Cantilever QR Mount — 3-Inch Offset with Quick-Release

Similar to the ADR, the ADR-X mount is designed for mounting telescopic sights for 30mm tubes onto a flattop style AR-15 rifle. The 3-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. The extended 3-inch cantilever on the ADR-X provides an extra inch of offset compared to the ADR model and is best suited for scopes with four inches or more of eye relief.


The ADR-X mount features the Auto Lock Lever System and has the following advantages:

  • Does not require proprietary tools for adjustment.
  • Can be adjusted with your finger or a flat blade screwdriver.
  • Lever can be configured to lock to the front or the rear.
  • Superior clamping surface to insure maximum rail engagement.

Materials and Construction

The ADR-X mount is precision Computer Numeric Controlled (CNC) machined from a solid block of aluminum and finished in a hard coat anodize for a rock-hard, lasting finish.

  • Precision machined from 6061 T6 aluminum.
  • Hard coat Type 3 Mil-Spec anodized for a lifetime of performance.
  • Fully adjustable to fit both in and out of spec rail systems.

The ADR cantilever ring mount positions the center of the riflescope tube at a height of 1.47 inches (37.34 mm) from the base. Weighs 8.4 ounces. Made with pride in the U.S.A.
