Few scope bases designed to fit the factory-drilled holes in Ruger 10/22 receivers mount low enough to allow the use of the guns’ original barrel-mounted iron sights when an optic is not attached. One that does is the Mounting Solutions Plus machined-aluminum See Through Mount Mil-Spec Picatinny.
Its low-profile design allows a red-dot or scope to be mounted as low as possible to the receiver, and a groove machined the length of the mount’s center allows full use of the gun’s factory iron sights.
The 4¾"-long mount features 12 cross slots, is secured to the receiver with four included screws and is available in black- or silver-anodized finishes.
