Lost track of where it was in the other thread, but....

I can see it !

Battery powered compressor in the butt stock, capable of about a modest 4:1 compression ratio.
Hand-pump a chamber that provides air into the compressor, to about 1000 PSI.
Supercharged output toward the valve, 4000 PSI !
Volume ? How much do you want to pump and pre-charge the compressor !?

Interesting.
Lesseee.....
Space for K-mart tire pump compressor. ( 250 PSI model, about 17:1 max compression ratio )
Ten "D" batteries to run the compressor....

In my head, it all fits into the butt stock of a rifle.

Still working on how to cram it into a pistol.
AAA batteries, maybe....

OR....... ( just occurs... )

TWO pump arms.
One for precharge, and one for supercharge !
No more difficult that driving a Mac duplex transmission.
