a question about bb sniper rifles

[elad311]

In bb guns like the sniper rifle, how can it shoot at least 5 shots without
spending all the air in the chamber?
and why only 1 shot doesn't taking out all the air?

and why only 1 shot doesn't taking out all the air?

When you take a shower, you don't drain the entire water system the second you open the tap

If you have a valve that opens and closes instantly (like say, a hammer or manually operated blowgun valve), it will only release a small amount of the pressurised air in the chamber, leaving enough air for subsequent shots.

Is this valve DIYable?

Refer to your other thread. - All you need is a blowgun with a chamber at one end and a barrel at the other.

But blowguns don't open fast!

Ah, but everything in life and spudding is relative. You wouldn't use a blowgun as a main valve for a 2 inch calibre cannon, in that case yes, blowguns don't open fast! When it comes to 6mm BBs however, with enough pressure behind them and a long enough barrel, a simple blowgun could be enough for your purposes.

If it can put a lead pellet through a tin can at point blank range as shown in the other thread, then it is certainly good enough for airsoft sniping. What sort of performance are you expecting from this design? If you want multiple shots from one chamber and don't have too many resources in terms of HPA/CO₂ tanks, chances are you're going to have to make a compromise when it comes to performance anyway.
