Geissele Automatics 30Mm 1.3'' High 0 Moa Ar-15 Power Extended Mount

The Geissele Automatics 30mm 1.3" High 0 MOA AR-15 Power Extended Mount is a precision scope mount built for shooters who demand rock-solid repeatability on their tactical or long-range platform. Machined from solid 7075-T6 billet aluminum, this mount offers the rigidity and durability required to keep your optic zero'd shot after shot, whether you're running a competition rifle, hunting rig, or precision bolt gun. The 0 MOA picatinny-compatible design means your scope mounts level to your barrel, letting you maximize your turret adjustment range downrange.

What sets this Geissele mount apart is its extended seven-section rail footprint, giving you the flexibility to dial in eye relief exactly where you need it. That extra real estate matters on crowded AR-15 uppers where you're juggling magnified optics, battery compartments, and sometimes a charging handle in awkward places. You get the freedom to mount your glass without compromise, and the black anodized finish resists corrosion through years of field use and storage.

The 30mm tube diameter keeps your options open for mainstream hunting and precision scopes, and the 1.3-inch mounting height clears most AR handguards and cowitness solutions. Geissele backs this build with their signature nut-and-bolt securing method—four shear lugs lock the mount to your upper receiver rail with zero flex. That's the kind of engineering philosophy that made Geissele a name trusted by military armorers and competitive shooters alike.

Frequently Asked Questions

Will this mount work on my AR-15 upper?

Yes. The Geissele mount uses a standard picatinny rail interface and is secured with a nut-and-bolt method. It fits any AR-15 upper with a flat-top picatinny rail.

What scope tube diameters does this mount support?

This mount accepts 30mm scope tubes—the most common diameter for modern hunting and tactical optics.

Does the 1.3-inch height work with a cowitness red dot?

The 1.3-inch height allows for cowitness capability with many AR-height sights, depending on your specific optic and sight combination. Verify compatibility with your exact setup before ordering.

Why does 0 MOA matter?

A 0 MOA mount aligns your scope level with your barrel bore, allowing you to use the full range of your scope's elevation turrets for long-distance adjustments rather than burning adjustment clicks just to zero at 100 yards.
