AeroPrecision
The Aero Precision 34mm Ultralight Extended Scope Mount is a single-piece base-and-ring combination designed for shooters who refuse to carry extra weight without reason. Built for AR-pattern rifles with Mil-Spec 1913 Picatinny rails, this extended scope mount pushes the rear ring forward by 1 inch—a geometry that opens up eye relief and helps you find a comfortable, repeatable cheek weld behind optics that demand precision. Whether you're setting up a lightweight hunting rifle, a precision range gun, or a duty-ready AR, a well-engineered scope mount is the invisible foundation of consistency.
At just 4 ounces, the Ultralight lives up to its name and proves you don't have to choose between strength and weight savings. The design uses a cross-slot keyway that resists recoil shock, and the entire mount is machined from 6061 T6 extruded aluminum—a material choice that balances rigidity with minimal mass. Made in America, it comes anodized black and uses a straightforward 15 in-lbs screw torque spec for installation. This is the kind of mount that disappears once it's mounted; it does its job and gets out of the way, which is exactly what you want when you're focusing on fundamentals.
Aero Precision's Ultralight line has earned a reputation among serious AR builders for combining no-frills design with proven reliability. If you're building a rifle where every ounce matters—a backcountry rifle, a match gun, or simply a smarter setup—this extended mount delivers the support your scope needs without the bulk.
| Scope Ring Size | 34mm | |
| Mount Profile | Extended (1-inch forward offset) | |
| Material | 6061 T6 extruded aluminum | |
| Finish | Anodized black | |
| Weight | 4 oz | |
| Rail Compatibility | AR-pattern Mil-Spec 1913 Picatinny | |
| Screw Torque Spec | 15 in-lbs | |
| Configuration | Integrated 1-piece base and ring |
Yes—the Aero Precision Ultralight Extended Scope Mount is designed for any AR-pattern upper receiver that features a standard Mil-Spec 1913 Picatinny rail, which includes both .223/5.56 and .308/7.62 platform rifles.
Extended refers to the forward offset of the rear ring—in this case, 1 inch ahead of the base position. This geometry moves your eye farther back from the rear lens of the scope, which provides better eye relief and helps you achieve a more natural sight picture and cheek weld, especially on rifles with less rail real estate or when using higher magnification optics.
The 34mm ring diameter is designed to fit scopes with 34mm tube bodies. Before ordering, verify your optic's tube diameter—it should be printed on the manufacturer's spec sheet. Common tube sizes are 30mm, 34mm, and 35mm, so double-check to ensure a proper fit.
The Aero Precision Ultralight mounts to your rifle's Picatinny rail using the integrated clamp mechanism. Torque all fasteners to 15 in-lbs using an appropriately sized wrench or torque wrench. Hand-tight plus a quarter turn is a good rule of thumb if you don't have a torque tool on hand, but proper measurement is always better.
