American Defense Delta 30mm Scope Mount - Precision 1.7" Height Tactical Optic Mount

The American Defense Delta 30mm scope mount is a cantilever-style optic mount built for AR-15 flat-tops and other tactical platforms where you need the glass mounted high and far forward. At 1.7" of height, this mount clears iron sights, accessories, and most importantly, gives you the room you need if you're running night vision or a gas mask underneath. Whether you're building a rifle for precision work, low-light hunting, or serious field use, the Delta puts your scope exactly where it needs to be—with 2" of eye relief built in to keep you comfortable behind magnified glass.

Built from 6061 T6 aluminum and finished in hard-coat Type 3 mil-spec anodize, the Delta is engineered to survive hard use without flinching. The horizontal split rings grip 30mm tubes securely, and the spacing between rings (4.4") accommodates standard scope tube lengths without binding. American Defense's patented QD Auto Lock Lever system is the real workhorse here—it's tolerant enough to lock down both in-spec and out-of-spec Picatinny rails, so you don't have to hunt for the perfect rail system. Adjustment is straightforward: no proprietary tools required. A flathead screwdriver or your fingertip is all you need, and the lever itself can be configured to lock toward the front or rear, depending on your setup and how you like to work your rifle.

This is the kind of mount that doesn't advertise itself but proves its worth every time you shoulder the gun. No fuss, no special requirements, no gimmicks—just a solid, fast-locking optic platform that gets out of the way and lets your rifle do its job.
