Crosman 22XX/13XX/PC77 Rear Sight Blades

thingiverse

This is a collection of replacement rear sight blades for the Crosman 13XX/22XX series of airguns. They directly replace part [OS244.](https://www.gunspares.co.uk/images/categories/24345.gif "#OS244") These are designed to fit very snugly into [AlanMoulding's Steel Breech Rear Sight.](https://www.thingiverse.com/thing:4350389) Depending on the dimensional accuracy of your printer, you may have to sand the part a bit before it fits well. Remember to slide the blade into the rear sight from the top instead of trying to press it in flat side first. If you're using the stock Crosman rear sight (for the plastic breech), you may have to print the blades slightly scaled up (101%-102%) to have a tight fit. Currently includes: - Stock-alike: Roughly the same dimensions as the standard Crosman rear sight blade. Includes a peep sight and regular Patridge posts. More or less a direct copy of the original part. - Shortened: Includes both a peep sight and Patridge posts, but is significantly shorter than the stock rear sight blade. [Designed to allow installation on a gun with a convex end cap, which would otherwise get in the way of the blade.](https://i.ibb.co/8jBzbD4/Short-Blade-Problem.jpg "Designed to allow installation on a gun with a convex end cap, which would otherwise get in the way of the blade.") - Notched: Variation of the shortened blade. Includes a U-notch and a V-notch. Print with a brim if you experience corner lifting. - Ghost Ring: Variation of the shortened blade, with a shotgun-style ghost ring. More variations to come if/when I find the time.
