Aero Precision Ultralight 34mm One Piece Scope Mount Black, SPR

The Aero Precision Ultralight 34mm One Piece Scope Mount is purpose-built for AR-platform rifles where every ounce counts and precision matters. Engineered for shooters who refuse to compromise between weight savings and rock-solid optics support, this SPR (Special Project Rifle) mount delivers the rigidity you need without the bulk that slows you down. Whether you're running a competition rifle, a long-range precision build, or a lightweight hunting AR, this single-piece design offers a time-tested solution for mounting quality optics on Mil-Spec 1913 Picatinny rails.

What sets this mount apart is its thoughtful engineering: the rear ring sits 2 inches forward compared to conventional designs, giving you better eye relief and a more comfortable shooting position. That positioning matters whether you're behind the gun for six shots or six hours. The cross-slot keyway design grips your upper receiver and resists recoil without relying on excessive weight. At just 4.1 ounces, this is genuinely one of the lightest single-piece 34mm mounts you'll find—a real advantage if you're building a dedicated lightweight rifle or want to preserve the balance of a precision platform.

Made in America from 6061 T6 aluminum, the mount arrives in anodized black and is built to handle field use. Installation is straightforward: just torque the mount screws to 15 in-lbs and you're done. This is the kind of no-nonsense accessory that works quietly in the background, doing exactly what a mount should do: hold your optic still and get out of the way.

Frequently Asked Questions

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

Yes, the Aero Precision Ultralight 34mm mount is designed for any AR-type upper receiver equipped with a Mil-Spec 1913 Picatinny rail. That includes standard AR-15s, AR-10s, and other modern sporting rifles with the correct rail profile.

What's the benefit of moving the rear ring forward 2 inches?

The forward-positioned rear ring improves eye relief, giving you a more comfortable cheek weld and better sight picture, especially during extended shooting sessions. It also tends to balance the sight picture more naturally on most shooters' faces.

How much does this mount weigh?

At 4.1 ounces, this is one of the lightest single-piece 34mm mounts available. For shooters building lightweight hunting rifles or competition guns where every gram counts, that weight savings adds up across the entire platform.

What scope ring size do I need for my optic?

This mount is designed for 34mm scope tubes. Before purchasing, verify your optic's tube diameter—common sizes are 1 inch, 30mm, 34mm, and 35mm. This mount will not fit smaller or larger diameter tubes.
