So I'm sick of making really gross builds because of my horribly limited resources. They're never airtight and usually end up with a much lower power than I desire. I had an idea for a full auto gun with a detent and would like some feedback before I actually try and make it.

So the general idea is this:
Pressure washer gun threads onto some Male/Female size reducer, that brake line can thread into (the flared end tubing with those hexagonal slip/thread deals on them). The Brake Line is a very short piece that then threads into an appropriately sized nipple (sawed off if need be), with an O ring sandwiched between the fanned end of the brake line and the fanned end of another piece of brake line coming out of the nipple which is the barrel. Mostly I want to know if this detent would be effective/airtight (proovided I epoxyed or loctited the threaded deals on the brake line so [hopefully] air couldn't escape.

And as far as a magazine goes:
Introduce a T fitting before the brake line (perhaps direcly after the pressure washer gun). Pipe comes off the top part of the T, perhaps a ball valve, more straight pipe and then a removeable threaded cap? I don't know if the BBs would be agitated enough or what though.

Yeah that should work. Give it a shot. Just be ready to possibly put in more pressure than 100 psi...

If the o-ring is properly compressed, you shouldn't need to seal the threads to avoid leaks.

The problem with o-ring detents and BBMGs though...

So you think BBs would actually flow instead of just sitting on the bottom of the T letting air pass over them?

I'm scared because the airs input and output would be inline.
Maybe if it was filled over halfway idk.

If you're putting enough air in it should work.
