It would be uncomfortable to operate if you ask me.

Also the spring would need to be so ridiculously strong, that the trigger pull to fire the tank would simply be too dificult.

Well I don't know about that hard, but it certainly wouldn't be easy. Also, the idea of the air release valve being constantly pressed in, concerns me about air leaking. You might as well just run the bladder straight into the air tank, no release valve. You'll lose a little air, but it will be true semi-auto.

Might I ask where I could find the check valve that you used in this design?

Should be available from most pet stores, look in the aquarium section.

Great, thanks! I wouldn't have thought to even look at a pet store, but now I see.

Nicely done but how many pumps does it need? If it's too many like the original 25 pumps then this isn't war practical.

Theory. Why not relocate the fill button to face the front of the trigger, and make an epoxy putty tab to hit the button when the trigger is released, thus truly making it semi-automatic?

Even though you're banned now, note that it won't be 25 pumps for one shot, but 25 for five shots. 25/5 = 5, so on average 5 pumps per shot.

Only question I have is how much pressure would be required to press the button, because the spring holding the trigger forward will have to provide that pressure.

Well he can always install a secondary spring. Stiffer trigger pull for semi-auto? Yes please.

I didn't bother with it when this thread was necro'd for a direct question, and that question was answered, but from this point forward anyone who posts will be treated like they're reviving a months-old thread. (ie don't post unless you have something significant to add.)
