The American Defense AD-DELTA-C 34mm Cantilever Scope Mount, High Height is an American Defense Mfg. lightweight cantilever quick-detach scope mount, with 34mm rings at high height, machined from 6061-T6 aluminum with a hardcoat anodized finish and made in the USA. It clamps with ADM's patented Auto Lock quick-detach lever, which self-adjusts to in-spec and out-of-spec Picatinny rails without tools and returns to zero when refitted.
How It Compares
The DELTA-C is the skeletonized cantilever — the same Auto Lock clamp and cantilever geometry as the AD-RECON cantilever mount, with metal removed where it is not carrying load. The range also covers AD-DELTA-C 30mm standard height and AD-DELTA-C 30mm medium height and AD-DELTA-C 34mm medium height. If you want the heavier full-section mount, take the AD-RECON; if you need the scope set back over the receiver by a full 3in, take the AD-RECON-X extended cantilever mount.

Frequently Asked Questions
Which scope tube does this mount take?
It takes a 34mm scope tube.
What rail does this mount fit?
It fits a MIL-STD-1913 Picatinny rail, and the Auto Lock lever self-adjusts to both in-spec and out-of-spec rails.
Does this mount return to zero after removal?
Yes. It uses American Defense Mfg.'s patented Auto Lock quick-detach lever, which self-adjusts to the rail and returns the optic to zero when refitted, so it can be taken off for travel or cleaning and put straight back on.
What height is this mount?
This is the high-height version. American Defense lists the AD-DELTA-C in several heights and in both 30mm and 34mm ring sizes, so choose the height that clears your objective bell.
How does this mount differ from the AD-RECON?
The AD-DELTA-C is the lightweight, skeletonized cantilever; the AD-RECON is the full-section version. Both use the same Auto Lock quick-detach clamping system.
