The bolt is what controls the bb feeding.

no, the spring assembly can be taken out of the bolt housing, which feeds the bb's.

Like I said, blow forward bolt and you should be able to change it out with the spring assy if you want.

What? All I am doing is taking out the spring and piston, and attaching a QEV this the nozzle on the inside of where the spring, and piston used to be, EVERYTHING else on the gun will stay the SAME. not blow forward bolts.

Did you read the post that I sent to Wyz?

QEV won't fit where you are proposing. Maybe you could feed a hose or a small fitting to the barrel.

again, that's not what I'm doing, I am simply utilizing the internals already found inside of the sniper rifle, I am just replacing the spring powered piston with a large-ish chamber, a 3 way valve, and a QEV

Should be the Sherline logo ;)

A 1/8" QEV should suffice for airsoft, and even with compressor (roughly 150 psi) pressures, your chamber might be a little too big. If this is for skirmishing, what you want is consistency and efficiency, so ramping up the power excessively will only waste precious gas.

Again, this is a bolt action sniper rifle, made for one shot, one "kill," I don't plan on spraying people with semi auto, but I do know a way to make it semi auto, but that will come later.... and since it is bolt action, the gas usage is at a minimum, and since I will be using low pressure (40-80 PSI) the large chamber should be fine. The large chamber also adds a nice weight to the gun.

Evan, I highly suggest you look at the blow forward bolt. The QEV idea has little potential, trust me, I have tried. If you really want it to work, you will have to design a gun around the inner workings.

THAT'S WHAT I'M DOING!! I'm just utilizing the mechanics INSIDE of the gun in order to have a reliable loading system!!

Ok... Well have fun figuring out how to pull the bolt back along with a qev and chamber and trigger and the list continues...
