Classic Rear Sight Base. XL Base .830" to .930" is currently out of stock. Smaller sizes availabe that can be fit to larger barrel diameters. 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"
