Thanks, not sure if it's me or Amazon that messed up but some of them seem a bit longer than I needed.

You can't post a picture like that without showing us your setup!

Also, it makes one feel insignificant in the vastness of it all, while simultaneously conveying a sense of freedom.

DRO galore! Finally received these things and can start thinking about mounting them.

Correct me if I am wrong but I believe the bars can be cut down to size without issue, yes?

Playing with the idea of a piston actuated semi automatic airsoft, there will be a spring behind the piston to return it to the home position which will allow another to drop into position, detent may be needed to stop it rolling out. Not sure what will happen to the piston as it reaches full strok...

How would hollow cylinder and sabot go. Someone's thought about it. "Cookie Cutter" tubular bullets exist, but they need to be fired from a rifled barrel: https://i.imgur.com/FVnC5zY.jpg Light projectiles with very high velocity and good ballistic coefficient due to the low frontal area. They were ...

Only question I have is how does he vent if before the next shot? Good question, there doesn't seem to be a fan or anything. At about 11 minutes you can see there's a line connected to the chamber, maybe he's injecting compressed air? The reloading mechanism reminds me of those automatic mortars: h...

Welcome to the forum and interesting concept!

I am reminded of the M18 recoilless rifle that had a less conventional grip setup:



Perhaps a sight mount of sorts would be useful.

The trigger you actually draw is the initiator of the recharge of the repeat hybrid. It is the mechanical locking of the piston, which allows it to move to the right, by the action of the spring, and then, to the left by the action of compressed air. To fire, the trigger is the piezoelectric. What ...

Sometimes it ends up back in the chamber...

Tiger Tank workshop manual on the filing cabinet, lol, I got that in PDF. I have this in hardback... https://i.imgur.com/291GT2f.jpg To tie with what is said in the video, I am a great admirer of what comes out the German compulsion to do things "properly" resulting in something big, complicated, b...

A little slow motion study of a classic CO2 shotgun: https://youtu.be/WTx04U4Tvg4 When the button under the stock is pressed, the whole barrel moves forward under spring pressure, pulling the cartridge with it as it is held in the breech by friction. The rim of the cartridge then caught on the eject...

I found this quite interesting:



The Tank Museum's channel in general is worth looking through, a lot of illuminating material that is very well presented.

A good diagram of how it works

I was having a bit of a think about this idea and it seems it could be greatly simplified and also made more efficient:



The piston itself becomes the hammer that opens an inline balanced valve.
