I have one of John's tanks and it does have the blow out disk for the output side and the other for the full tank pressure.
I have a qb79 with a 1200psi tank from Matt Bean and it shoots a lot slower than a qb78 supplied with the same psi via remote.It doesn't have valve lock though because when you shoot it below 1200 it just gets slower.It shoots just over 700fps,the qb78 does that on co2 and 850 fps with hpa at 1200psi.It's a .22 cal with 14.5 gn superdomes.

I think Mike uses a trick valve spring..(taper wound?) that helps output - classicalgas on Jul 12, 2008, 11:09 AM
