Egw Ruger~ 10/22~ 20 Moa

The EGW Ruger 10/22 20 MOA scope base transforms your rimfire into a precision shooter by adding a modern Picatinny rail system without any gunsmithing. This one-piece aluminum base mounts directly to your 10/22's factory receiver holes, giving you the flexibility to run virtually any Picatinny or Weaver scope ring and optic combination. Whether you're setting up a casual plinker or a serious small-game hunting rig, a 20 MOA base opens up holdover options for extended-range shooting on a .22.

Built from 6061 T6 extruded aluminum and precision-machined to MIL-STD 1913 specifications (±.002"), this mount delivers the rigidity you need for consistent accuracy. The full-width Picatinny slots accept any standard ring system, so you can adjust eye relief quickly or swap optics without breaking out tools. EGW's milled center channel keeps weight to a minimum—a smart detail for a rifle that might spend hours on your shoulder during a day afield.

Installation is straightforward: the base uses factory receiver holes, eliminating the need to drill or tap. EGW includes socket head Torx screws and the wrench to do the job right. They recommend 20 inch-lbs of torque and a small amount of blue threadlocker for a permanent, vibration-proof fit. If you've been running open sights on your 10/22 or dealing with a clunky legacy mount, this rail base is the practical upgrade that opens the door to modern optics and better long-range capability.

Frequently Asked Questions

Will this mount fit my Ruger 10/22 without modifications?

Yes. The EGW base is drilled to align with the factory receiver holes on the Ruger 10/22, so no drilling or tapping is needed. Installation is a straightforward swap using the included Torx screws.

What scope rings do I need for this base?

The base accepts any Picatinny or Weaver scope rings, giving you plenty of options. This flexibility means you can choose rings to match your preferred optic and eye relief setup.

What does the 20 MOA mean, and why would I want it?

The 20 MOA elevation is built into the base's angle, giving you additional upward adjustment range on your scope. This is useful for extended-range shooting where you'd otherwise run out of turret clicks; it's commonly used in long-range rimfire setups to maximize the utility of your optic.

What's included in the box?

The mount comes with socket head Torx screws and the wrench needed for installation. EGW recommends applying blue threadlocker to the screws and torquing them to 20 inch-lbs for a secure, vibration-resistant fit.
