Re: "Sabotless" Semi-Automatic Shotgun Concept

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 ...

Crosman Trapmaster Shell Ejection

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...

The question "what is the best tank?" as a way of examining engineering stereotypes

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.

Re: "Sabotless" Semi-Automatic Shotgun Concept

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.

Re: Pull Trigger, loads, then releases chamber?

Here is one working:



Looks like it is basically the same concept as a NBB airsoft gun.

A double action trigger seals the chamber and then knocks open a valve poppet.

Re: Blow forward AEG nozzle... Why it didn't take on?

How does a Non blow back work? Is that like the trigger pulls nozzle loads bb Seats bb. And somehow blocks air input and releases chamber?. More or less, it depends on the model. On my Marui MK23 the trigger pushes a nozzle forward that strips a BB from the magazine and least it in the barrel, whil...

Re: Short question topic

I feel that such losses are probably not that significant. Pistons typically have a large surface so they do not require a high pressure to move. Added to that, their travel is usually very limited so the increase in chamber volume relative to the total is minimal.

Re: Blow forward AEG nozzle... Why it didn't take on?

Interested in thoughts why think they stopped making it. /discontinued. Or if anyone knows why not good in AEG gearbox. Probably lack of power. Blow forward valves work well but since they need to be activated before the shot is fired, they lower gas pressure significantly meaning there is less pre...
