Geissele Automatics 30Mm Ar-15 Hyper Extended Ddc Mount

The Geissele Automatics 30mm AR-15 Hyper Extended DDC mount is a precision scope mounting system built for shooters who demand absolute return to zero and rock-solid repeatability on the range or in the field. This is a billet-aluminum mount machined from a single piece of 7075-T6 aluminum, then finished in Geissele's Desert Dirt Color (DDC) type 3 hard coat anodize—a durable, low-reflective coating that pairs well with modern AR-15 setups. Whether you're running a dedicated precision rifle, a hunting AR, or a general-purpose fighting gun, this mount delivers the clamping security and mechanical consistency that serious shooters expect from Geissele.

What sets Geissele's Super Precision line apart is the engineering philosophy behind it. The entire mount is machined as one billet, which allows for internal pockets and ribs that reinforce the structure without excess weight. The nut-and-bolt clamping system—Geissele's update on a classic attachment method—applies 1,400 pounds of clamping force per bolt pair, far exceeding the hold of quick-lever mounts. This means your scope stays put, shot after shot, without fear of creep. The mounting surface spans seven Picatinny sections and incorporates four shear lugs for additional mechanical security and alignment. Geissele line-bores the scope caps to the body and serializes them together, ensuring the tightest possible fit and allowing you to torque your scope rings with confidence.

The Hyper Extended configuration positions your optic further forward on the receiver than standard mounts, a setup that works well for longer-range builds, enhanced sight picture angles, or shooters who prefer a more forward scope placement. This mount carries zero MOA by default, meaning it tracks the natural point of aim of your AR-15 upper receiver, though 20 MOA cant options are available separately if your build demands it.

Frequently Asked Questions

Will this mount work with my AR-15 upper receiver?

Yes. The Geissele 30mm AR-15 Hyper Extended mount is designed for AR-15 and M4 platform rifles equipped with a Picatinny rail on the upper receiver. It requires a standard AR upper with Picatinny slots to mount.

What size scope tube does this mount support?

This mount is built for 30mm scope tubes. Do not use it with 1-inch or other tube diameters.

How does the Hyper Extended configuration differ from a standard mount?

The Hyper Extended configuration positions your scope further forward on the receiver compared to standard mounts. This is popular for long-range precision builds, tactical carbines, and shooters who prefer a more forward sight picture or need additional clearance between the rear scope cap and their charging handle or upper receiver.

Is a 20 MOA cant available for this mount?

Yes, Geissele offers this mount in both zero MOA and 20 MOA cant options. The version described here comes with zero MOA canting; if you need 20 MOA, that variant is available as a separate product.
