Geissele Automatics 34Mm Ar-15 Hyper Extended Ddc Mount

The Geissele Automatics 34mm AR-15 Hyper Extended DDC Mount is a precision scope mount built for shooters who demand rock-solid repeatability on the precision rifle range or in the field. This is a billet aluminum mount engineered to hold zero shot after shot, built from a single piece of 7075-T6 aluminum and finished in Geissele's Desert Dirt Color (DDC) Type 3 hard coat anodize—the same finish trusted by professional shooters and military units for its durability and low-profile aesthetics.

Where this mount separates itself is in the engineering. Geissele machines each mount as a complete unit, allowing them to integrate pockets and ribs throughout the structure for maximum rigidity. The caps are line-bored to the body and serialized, ensuring a precision fit that lets you apply proper scope torque without fear of crushing the tube. That precision matters: when you're dialing elevation and windage adjustments, you need confidence that your mount will return to zero repeatably. The mounting surface spans 7 picatinny sections and uses 4 shear lugs to distribute load. Clamping is handled via Geissele's proven nut-and-bolt method—not a quick-release lever—delivering 1,400 pounds of clamping force per nut-and-bolt pair. It's overkill in the best way: the most mechanically secure method of attaching a scope to your weapon system.

The Hyper Extended configuration is built to accommodate a wide variety of scope geometries and objective bell sizes, so whether you're running a compact 1-4x or a long-range 4-16x, you'll find a cap location that works. The mount is offered in zero and 20 MOA cant options; verify which you need before ordering.

Frequently Asked Questions

What rifle platform is this mount designed for?

This mount is optimized for AR-15 and M4 platforms with picatinny rail on the upper receiver.

Will this mount fit my scope?

This is a 34mm ring mount with extended cap geometry designed to fit a wide variety of scope tube diameters and objective bell sizes. Verify your scope's tube diameter (this mount is 34mm) and check that the cap locations align with your specific optic before ordering.

What's the difference between the zero and 20 MOA options?

The 20 MOA cant option incorporates a 20 minute-of-angle upward angle built into the mount, which extends your rifle's elevation adjustment range for extreme long-range shooting. The zero option sits flat on the rail. Choose based on your shooting distance and rifle setup.

How secure is the nut-and-bolt clamping system?

The nut-and-bolt method provides 1,400 pounds of clamping force per pair—significantly more force than quick-release lever systems—making it the most mechanically secure way to attach a scope to your gun. This translates to superior return-to-zero performance shot after shot.
