Description
The EGW Winchester 52 Target Picatinny rail is a purpose-built scope base that brings a modern mounting system to some of the most respected smallbore rifles ever made. It's a one-piece design machined from domestic 6061 T6 extruded aluminum, then finished in matte black anodizing for durability and a clean, low-glare look. At 0 MOA cant, it's set up for flat shooting inside roughly 150 yards, which covers the bulk of rimfire target work and benchrest practice.
What the Winchester 52 Target Rail Fits
This mount was engineered specifically for the Winchester 52, but the bolt pattern covers a surprising lineup of classic rifles. It fits the Winchester 52 and 75, Kimber 82C and 82G, H&R M12, Remington 37, and BSA Martini Mk2 and Mk3 actions. It will also work on an Anschutz 54 and 64 provided the rifle has the Unertl barrel blocks. One note on barrel profile: the 0 MOA version is correct for rifles whose barrel does not taper below .750 inches at the muzzle end. Rifles with a thinner tapered barrel use a different cant in the EGW lineup.
Built Around the Picatinny Standard
The full-length Picatinny cross slots give you real flexibility when positioning rings, so you can dial in eye relief for just about any scope you want to run. It's compatible with both Picatinny and Weaver style rings, which makes sourcing a ring set easy. A machined channel down the center trims weight, keeping the rail right around 2 ounces, and in many cases it won't block the use of factory iron sights. Owners of older target rifles often turn to this rail to step up from limited 3/4-inch tube side mounts to a full-size modern optic.
Installation Notes for the Winchester 52 Mount
The rail ships with #6-48 x 1/4 inch mounting screws and a T-10 bit, so you have what you need to get started. You'll remove the existing barrel blocks and the mount screws into the barrel. EGW recommends torquing to 20 inch-pounds with a drop of blue thread locker for a rock-solid hold. The entire mount and its hardware are made in the USA.

Frequently Asked Questions
Which rifles does the EGW Winchester 52 Target rail fit?
It fits the Winchester 52 and 75, Kimber 82C and 82G, H&R M12, Remington 37, and BSA Martini Mk2 and Mk3 rifles. It will also work on an Anschutz 54 and 64 if the rifle has the Unertl barrel blocks. Measuring your receiver hole spacing before ordering is always a smart move to confirm the match.
Should I get the 0 MOA or a canted version?
The 0 MOA rail is the right call for a Winchester 52 whose barrel does not taper below .750 inches at the muzzle. EGW recommends 0 MOA for shooting from 0 to 150 yards, which covers most rimfire target and benchrest work. If your barrel tapers thinner than .750 inches at the front, you'd want the negative 20 MOA version instead to bring the base back to level.
What rings work with this Picatinny rail?
The rail uses the standard Picatinny slot pattern, so it accepts any Picatinny or Weaver style rings. That gives you a wide range of modern ring and optic options compared to the old 3/4-inch tube side mounts these rifles originally used. Rings are sold separately.
Does it come with the hardware to install it?
Yes, it ships with #6-48 x 1/4 inch mounting screws and a T-10 bit. You'll remove the existing barrel blocks and screw the mount into the barrel. EGW recommends 20 inch-pounds of torque and a drop of blue thread locker for a secure, lasting hold.
