CROSMAN CUSTOM SHOP 1300KT PUMP PISTON fits 13XX
This piston is original to the Crosman Custom Shop 1300KT, P1377 and P1322. It's a nice upgrade for 1377, 1322, 2289G Backpacker and PC77 models. It fits the tube better than older versions, holds the cup seal tight and is made of a much higher grade of polymer. It generates more power with each pump due to being less flexible/compressible than older versions and slightly longer.
It does not fit older models with the pull-knob cocking mechanism and sliding breech cover.
We have replacement cup seals listed separately, they fit this piston and all of the earlier Crosman variants.
