Bullet Feeder Drop Tube Adapters for FLEX Conduit

Update: This does not work well for 9mm, I have changed to using pex and have posted this as well it may still work well for rifle bullets or longer bullets that can't tumble.

I couldn't find a source for springs for the bullet feeder. I created these to adapt for 1/2 PVC Flex conduit

Photo shows the original internal connection for the light barrier adapter, it has been revised for the flex to slide into it
