o-ring detente is not good for a vortex bbmg, I have tried some o-ring detente in a cloud bbmg, it needs +200 psi for the bbs to fire :shock: and the o-ring is already very easy for the bbs to pass. If you push the bb with you hand you won´t need any efforts at all, even through that it needs +200 psi, a pvc bbmg would explode

Crna, in theory it seems easy but when you actually put that in a PVC coupling without modification, it wouldn't be that simple. The taper would probably mess things up and the male threaded parts wouldn't go in far enough to seat the o-ring. On top of that, the o-ring would have threads around it, which could damage it and make seating not as easy.

I was thinking of plastic electrical fittings probobly should have said that :lol:, they have straight threads and I said he would need to mod the coupling so yeah. I do think it would be better to use sheet rubber in place of O-rings because it would grip better.

Oh, ok. Sheet rubber would have to be precicely cut though.

That's why you ppl use rubber washers :)
Though o-rings are superior in terms of sealing (and, unfortunately, more problematic to mount)

Even a rubber washer would have to be cut down, unless your threaded fitting is way bigger than the barrel. Depends on the situation I guess. Rubber washer between metal washers is my favorite way.

i used some rubber sheet, sandwiched between 2 steel washers.
The washers had a 8mm hole, and i poked a 4mmm hole in the sheet rubber.

This worked very well on my vortex block.... until the sheet rubber wore out, and was useless.

yeh but where would I get a threaded coupling in a similar size to my pipe, and the o-ring would just be glued between the threads correct? If I even used 1//2in pvc pipe it would be twice the size that I needed it.

Could I make a detent from a bb with a spring behind it intersecting the barrel, I saw that other places, but how would I make one.

here's some other ways of making a detent, silicone tubing is a good thing to have :) make sure the inner diameter is slightly smaller than your projectile diameter, for example 4mm ID tubing for 4.5mm BBs.
