Custom stock adapter which fits 1377 and 1322 Crosman models. Machined from 6082 T6 Aluminium. It is threaded 1 3/16 – 16 UN to accept standard buffer tubes. It has a power adjuster/ spring tensioner which can be adjusted with the key provided.
Fit with your existing screws. I include an Allen bolt which can be used to replace the rear grip frame screw to allow easier/better tightening of the unit. When fitting loosen the front grip screw a little to allow a bit of play while fitting the adapter and screws, once the adapter is fitted it can be re-tightened.
