Fit & finish are excellent--a great item! - Evolution Gun Works Picatinny Scope Mount, Winchester

This rail fits my Winchester 52D with target barrel perfectly. Thus far I have used it to try out three (3) different scopes, each with a different mount, with no problems whatsoever. A bonus is that while the rail does overhang the breech area, there is still plenty of clearance to load rounds comfortably from the right side, and there is also enough height to visualize the positioning of the ammo in the barrel when viewing from the left rear. I can recommend this item wholeheartedly.
