Winchester Short Stroke Kit

Pioneer Gun Works Performance Parts for Winchester Model 1873 Rifles

Winchester Short Stroke Kit with Carrier

*Notice* All of our parts made for Winchester rifles are designed to fit into the new Winchesters made by Miroku, not the original Winchester rifles
Our short stroke kits for the Winchester model 73 rifle come with a light weight aluminum carrier, and sells for $235.00. The lever throw is the same as that of our Super short stroke kit made for Uberti rifles. 

Our  Winchester short stroke kit will not work with Winchester's carrier. After testing Winchester's carrier, we have found that there are dimensional issues that interfere with the quality performance of our short stroke kit.


Winchester Light Firing Pin Extension

Our new Winchester light firing pin extension replaces the stock firing pin extension with all of it's safety devices, improving performance and reliability of your rifle.
