Crosman AS2250

[Cajun72]

Well found a AS2250 complete in box. Seals were bad, so ordered replacement seals and hpa tank adapter. Replaced seals, exchanged adapter, added gravmag adapter. Shoots great lots of shots, close to 700 fps, need few more mods to squeeze out more.

I'm really surprised more airguns don't run back bottles.

It's not rocket science, paintball guns do it all the time.

Those are neat guns.
They were prone to leaks but poly seals should fix that.

Best method to increase power is higher pressure, bigger plenum and longer barrel.
Looks like you have a longer barrel already.

My home brewed 22 cal King RatCatcher would make over 800 FPS with a 20" barrel regged at 1400 psi.
Set to 750 FPS with a 14 1/2" choked LW barrel at 1400 psi.
It's my main pest gun and is super accurate with CPHPs and the 9 shot GravMag mag.

That's pretty bad-ss.
