CROSMAN CUSTOM SHOP 1300KT PUMP PISTON fits 13XX
This part was removed from a new Crosman Custom Shop 1300KT pump airgun. It is a perfect fit for all 1377, 1322, 2289G Backpacker and PC77 models. It fits the tube better than older versions, holds the cup seal tight and is made of stronger plastic. It generates a little more power with each pump due to being less flexible than older versions. This piston is also found in the new P1377, P1322 and may be in new versions of other models as well.
I have replacement cup seals for this piston listed separately.
