Classic Rear Sight Base. This rear sight base is the same one we use for our R-201 Classic Adjustable Rear sight. The beauty of this base is that it allows you to use any rear sight insert with a 16mm dovetail. This includes our "See-Thru" and the New "Moon" sight insert as well as many other sight inserts found on the "Toy Chest" page under "Special Items". The sight inserts are held in place by a dovetail clamp which is secured with a 6-48 Allen head screw. Loosening this screw and clamp will allow for windage adjustment. All steel construction with a black oxide finish. Uses a single 6-48 screw (Included).
Dovetail height over barrel is .200". Simply add the insert height to determine the overall rear sight height.
This base is offered in 4 barrel diameter ranges: Bases: R-201B-675 = Barrel diameter .600" to .675" R-201B-730 = Barrel diameter .675" to .730" R-201B-830 = Barrel diameter .730" to .830" R-201B-930 = Barrel diameter .830" to .930"
