Spring feed parts.

[GroovYChickeN 2.o]

Ok so after seeing lukes 12rd tube mod for SS bodies I got to thinking what I would need to turn it into a spring feed.

I know I would need a spring (duh) and the plunger part that pushes the balls down the feed tube but what else?

Also where would I go to get the parts I need?

In addition to what you listed you will need an end cap. On top of parts you are also going to need a groove and hole milled into the feed tube to allow for loading (see any picture of a Sydarm or other springfeed pistol).

Maybe a powerfeed plug type of surface on the front end?
