Evolution Gun Works Ruger® 10-22 Takedown Picatinny Rail Scope Mount Silver 10 MOA Ambid. The Ruger® 10-22 mount is made specific to the gun. This scope mount will fit the 10-22, 10-22 takedown and is lowered to allow for use of rear sight with mount mounted. Picatinny cross slots run the full length of the rail, which gives the shooter flexibility when mounting scope rings and other accessories. The channel in the center reduces the overall mass of the mount, weighing in at 2-3oz on average. EGW’s one piece scope mounts are the obvious choice for hunters and tactical shooters alike. This mount is silver anodized. This mount is a Picatinny-style base and compatible with Picatinny or Weaver scope rings. Installation: EGW recommends 20 inch lbs of torque and a drip of blue loctite (loctite is available through our website and is sold separately).
