Try it and find out. My one bit of advice is that 7" is not long for an air-powered gun. If the tank capacity is similar to that of a Titan's, then a barrel over 1' is needed.

Yes it would work, but it's just a Big Blast. So why not just buy one of those?
You're lacking alot of the specifics needed to actually make something that works.

The little critters of nature, they don't know that they're ugly. That's very funny, a fly marrying a bumble bee. I told you I'd shoot, but you didn't believe me. Why didn't you believe me?

Erm... How does the trigger release the pressure? That's a very complicated system that you dumbed down into nothing. You say nothing about a valve... And conceiving and making them are both difficult processes; I recommend using an electronic sprinkler valve for your first home made.

The system used here is a copy of the 4B and LBB firing systems. Basically, the tank is divided into two chembers with pipes connecting them (no valves in between, but a cavity is created between the two main chambers for a valve). The valve that dumps the entire tank into the barrel is simply a piece of plastic or other material that forms a seal with a flat surface. The piece is placed inside a lip on the foremost chamber so it can slide back, but not pop out into the barrel. A firing pin extends from the back of this sealing part and into the cavity between the two tank portions. The trigger has a catch face that pulls this bar back against the pressure in the tank and opens the valve.

Advantages:

No springs for the valve itself are needed, the pressure will hold the passage shut.

It is simple to make and cheap compared to other HOMEMADE valves (definitely not practical with store-bought comparisons).



Disadvantages:

The valve needs to be opened against the pressure in the tank, which can lead to problems with high pressures that limit your overall operating limit.

If the valve gets stuck (I.e., the firing pin gets bent and can no longer retract back into the tank), the system is useless.

It is not practical compared to commercially sold valves, especially automatic ones.
