The EGW Winchester 52 Target scope base gives you a modern Picatinny rail mounted directly to your Winchester 52 receiver—no gunsmithing required. If you're running a vintage .22 target rifle and want to mount modern optics without permanent modifications, this one-piece aluminum base threads into the factory scope mount holes and gives you the flexibility to dial in eye relief and swap between rings or optics in seconds. It's the practical middle ground between keeping your gun original and running current glass.
Built from 6061 T6 extruded aluminum, the base is precision-machined with Picatinny slots gauged to military standard (MIL-STD 1913) at +/−.002" tolerance. The milled center channel reduces weight without sacrificing rigidity—important when accuracy is the game. Picatinny and Weaver rings both fit, so you're not locked into one mounting ecosystem.
Installation is straightforward: the base uses factory holes, comes with socket head Torx screws and the wrench to install them, and EGW specs 20 inch-lbs of torque with a drop of blue Loctite. If you're dusting off a Winchester 52 for precision rimfire work at the range, this base lets you modernize the sighting system without compromise.
