The American Defense AD-DELTA-C 30mm scope mount is a cantilever-style mount built for shooters who want flexibility in their AR-15 setup. If you're running a flat-top receiver and planning to stack glass, iron sights, magnifiers, or other accessories on the same rifle, a cantilever design pushes your optic farther forward on the rail—giving you better eye relief and the space you need behind the ocular bell to add those extra tools. The AD-DELTA-C delivers the strength and precision you'd expect from American Defense, without the weight penalty.
Built from 6061-T6 aluminum, this mount is light and rigid—qualities that matter whether you're dialing in a hunting rifle or setting up a duty gun. The 0 MOA base means you're mounting flat to the rail, making it compatible with optics already zeroed for that plane. At 1.5 inches of center-line height (with 30mm rings), the AD-DELTA-C positions your scope in a natural sightline for most AR configurations. The ring spacing matches American Defense's Recon mount, so if you ever decide to swap components, you've got options.
What sets this mount apart is the patented QD Auto Lock Lever system. Those standard levers lock solid to the Picatinny rail without fumbling or special tools—and they'll hold tight even if your rail is slightly out of spec, a real-world advantage on rifles that have seen use. You can orient the lever to lock at the front or rear of the rail, depending on your rail configuration and what feels natural to you. If you're building a rifle that needs to do multiple jobs, this mount gives you the real estate to make it happen.

The AD-DELTA-C is designed for flat-top AR-15 receivers with Picatinny rails. It mounts directly to the upper receiver rail system.
Yes. The cantilever design extends the scope forward on the rail, which opens up space behind the ocular bell. This lets you mount iron sights, magnifiers, and other rail-mounted accessories on the same rifle.
The 0 MOA base sits flat to the Picatinny rail with no upward angle. This is ideal if your optic is already zeroed for a flat-rail configuration; you won't introduce any additional elevation offset. If you're mounting an optic that requires an angle or has a different zero plane, verify compatibility before purchasing.
No. The standard QD Auto Lock Levers lock the mount securely to the rail by hand, with no special tools required. The levers can be positioned to lock at either the front or rear of the rail, depending on your setup.
