Yep that was my first piston valve.
And that is a different handle, I have a whole box full of them :tongue3:

Yeah I have a box full of nerf handles

LOL it was a joke, it's the same handle. What kind of loser has a box full of nerf parts... oh wait it's you... lol jk you should stick some on your guns then paint them, make then look cooler.

I buy them for like 1 buck at goodwill to loot for part, i used a nerf spring in my GB gun

I need to find a big spring for my GB mag (which is done now!!!!).

Make your own, theres plenty of posts about how to, I used a recon spring

Ok I'll see, it's amde to be a breech loader and a mag loader in one so its cool, back on topic now.

Now im worried the BFB will burst the PBs, Would an oring pad it enough

I don't think so, try to squish an o-ring with your fingers, you probably can't. Maybe some sort of foam disk would be better. Or possibly a few rubber washers.

Umm maybe a couple felt donuts

That would work too, but if it doesn't, you can always switch to marbles, plus they would do more damage cause they don't pop.

I can, but im starting to lean toward a QDV instead of a Machine Gun

Now you're talkin'!

Just need to work out the oring grooves

Use bolt/washer/lock nut combo and you don't need to!
