If you are planning to shoot your AR with a scope, you may want more eye relief than is normally offered by regular scope mounts. You need an extended scope mount to hold your optics in the right place. The Aero Precision Ultralight Extended Scope Mount is an exceptional offering in an ultralight extended scope mount for AR-15 receivers.

This Aero Precision Extended Scope Mount provides the eye relief you need without compromising the stability of your mount. By moving the rear ring of this mount an inch forward from the standard position and placing the forward ring on an extended arm, Aero’s engineers have pushed the scope forward without moving the mount base. Your Scope mount remains solidly set on the receiver rail and you get the eye relief you need without moving your mount base onto the handguard rail.

A precision engineered mounting base featuring Aero’s multi-point cross slot keyway makes installation of the Aero Precision Extended Scope Mount easy. Apply the mount base to your receiver rail, tighten three locking lugs and your mount is secure. Once in place, the mount base is virtually recoil-proof. Now add your scope and assemble Aero’s specially designed ring and you’ll be good to go. Aero Precision’s rings are joined at the top with a notched joint. This joint creates a lever effect so that as you tighten the rings there’s little chance for the scope to walk.

The Aero Precision Ultralight Extended Scope Mount is compatible with AR receivers that feature Mil-Spec 1913 Picatinny rails. It is available for either 30mm or one-inch scope tube sizes so you can secure all of your favorite scope with a quality Aero Precision mount.

The entire family of Aero Precision scope mounts is crafted on state of the art machining centers at their home in Tacoma, Washington. All Aero Precision scope mounts feature 6061 aluminum that keeps weight down and offers rigidity that won’t fail.

    Worked perfectly to mount a Vortex Viper 4-16x44 on an Aero Precision upper. No issues whatsoever mounting and looks great. Be sure to follow torque specs. Very happy with this mount.

  • Fantastic!

    This my second Aero Precision Ultralight Extended Scope Mount purchase. I believe this is the best scope mount available for an AR under $100. This mount will most definitely be my scope mount of choice for any future builds. It is a very high quality manufactured product. It is strong where it needs to be but yet very lightweight. All the edges and non-essential aluminum has been trimmed down with smooth precision. The scope rings are rounded and do not protrude or have edges like most rings that split horizontally. The Torx screws are high quality and the kit even includes a very nice Torx tool bit tool. This tool is designed with a small tab that limits over-torquing. If you need a lightweight non-QD scope mount, I highly recommend! (Get the extended version for an AR)
