Fits my 1322 or 1377 Crossman muilti pump air pistols (relatively new version from the sporting goods store) improving its accuracy as a packable bullpup without the length found in a shoulder stock.
With no real recoil, its not meant as a shoulder rest. This stock allows you to "grip the back of the stock" using the hollow below your collar bone and your cheek. Improving 1 handed shooting and more natural 2 handed than a pistol grip.
The upper breach screw needs to be replaced with one 1.1875".
There is a .3" hole. centered on the pump cylinder plug for a custom plug with threads or to add some support/stock strength with a steel, aluminum or composite support spar thru the stock. A common carbon fiber arrow can be used glued in place to true up the stock, adds stiffness, reduces heat warping and strength as a spine for the stock.
