Got the semi auto together enough to test fire, it seems to work, no magazine tube yet. The chamber and 1/2" valve are from my old 10mm ball bearing launcher so the air supply is probably over kill. The piston is from an old pneumatic cylinder that is cut down. The red block is aluminium. The princi...

I sort of made a full auto pistol from pieces I screwed together, the chamber is the only piece fabricated. Holds 130 bbs, rate of fire is insane, can get 4 bursts if I'm quick on the trigger. Compressor connects to the small fitting on the chamber at 150psi. The valve is a 5/2 1/8"' port pilot oper...

Made new piston from long 6mm bolt with head cut off and piece of 10mm thick nylon, works really good. Semi auto is now built in to my old single shot.

Finished with a T for loading, extended grip and a bit of paint.

I found the same with steel bbs, different barrels made no difference.

I'm concerned they had 90psi in it Bracing the barrel to the chamber would have helped, but still PVC is PVC and it will happen, this guy will find you

Finally got good internet after moving house, 100mbps

Came to see a Penguin

I've had that happen before, I put a T near the end of the magazine tube and supplied it with a small amount of air from the barrel (another T)
Sort of like this

No idea if it will work, but tinkering is a huge component of this hobby. Thanks! That's pretty much how I do it. I have added another T to that which makes it easier to load, I will do some videos some time, still settling in to a new house. https://www.spudfiles.com/download/file.php?id=29108&mod...

It's 2020, would you expect anything different, wait until next year at least.

Got a new toolbox for Xmas

So it's firing one BB every shot ? I made a semi-auto airsoft with a bolt which blocks the ammo feed tube which works great, now that it's sorted

And another transformation into Nerf Rival, mainly for the grandchildren to play with
BFG cut down and reshaped. Gravity fed tube holds 8 rounds.
