A safety valve for pneumatic installation that says 1.8K, how many bar or psi is it? It is a rupture disc of a pressure regulator and I do not understand when it is 1.8K ...
kilopascal ? Kpa. 1 Kpa = 0.01 Bar, 0.145 Psi. But 1.8K would be so low :shock:

Yes, just an open cylinder worked for me, 2 or 3" long.

In my experience it amplifies the noise significantly for the shooter too.
Yes, I've done that by mistake while making a dummy silencer for looks, and made a loudifier by mistake, a piece of 1" PVC pipe works really good.

Re: Semiauto Nerf Rival with no moving parts.

Re: Semiauto Nerf Rival with no moving parts.

This system worked perfectly for me, which is what makes 25 bb's of lead rise, caliber .22 in my replica of MAC 11. https://www.spudfiles.com/viewtopic.php?f=29&t=26856I used a small flow regulator to regulate the amount of air that rises through the tube that it keeps ammunition.

Semiauto Nerf Rival with no moving parts.

Testing an idea I had for a semiauto tube fed gravity feed and it seems to work, air goes up into the magazine and pushes the balls back up the tube because of a small amount of air bleeding out of the top of the tube, when the pressure builds up enough the front ball pops out like a cork as there i...

40mm is a pretty odd size here in the US but it'd be somewhat similar. Definitely a bit smaller.
40mm is the diameter of choice https://en.wikipedia.org/wiki/40_mm_grenade

Re: Spring powered Nerf blaster

The airsoft barrel slides inside the Nerf barrel and clamps at the front, changed the front grip and the charge handle again. Orange muzzle.
