The American Defense AD-DELTA-C Cantilever Scope Mount 30mm Standard Height is an American Defense Mfg. lightweight cantilever quick-detach scope mount, part number AD-DELTA-C-30-STD, with 30mm rings at standard height, machined from 6061-T6 aluminium with a hardcoat anodised 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 skeletonised 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 medium height and AD-DELTA-C 34mm medium height and AD-DELTA-C 34mm high 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. Compare the rifle scope mount range and all American Defense mounts in stock.

Frequently Asked Questions
Which scope tube does the American Defense AD-DELTA-C Cantilever Scope Mount 30mm Standard Height take?
It takes a 30mm scope tube.
What rail does the American Defense AD-DELTA-C Cantilever Scope Mount 30mm Standard Height 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 the American Defense AD-DELTA-C Cantilever Scope Mount 30mm Standard Height 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 the American Defense AD-DELTA-C Cantilever Scope Mount 30mm Standard Height?
This is the standard-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 the American Defense AD-DELTA-C Cantilever Scope Mount 30mm Standard Height differ from the AD-RECON?
The AD-DELTA-C is the lightweight, skeletonised cantilever; the AD-RECON is the full-section version. Both use the same Auto Lock quick-detach clamping system.
