Longshot pusher breech insert

The goal of this piece was to convert the stock longshot breech into a conventional pusher style breech with minimal modding effort.

This is a work in progress, I'm currently in the process of adding additional orings and tweaking the pusher, it's not feeding as well as I'd like

pusherout_09 I've filed down and installed in my longshot, pusherout_11 should not need filing. Currently it's hitting around 160 with old FVJs using a spring similar to 10/12KG workers and a 30cm long 13mm diameter alu barrel. I suspect it might not be as efficient as the conventional pusher kits on the market, but hey, it's like a 15min print vs a $60 kit.

EDIT: I have since learnt that this is old tech, a "universal breech" piece from like 2013ish, primarily in the Singaporean nerfing community, but it seems the files aren't available on thingiverse, so effort not completely wasted, I guess?
