leak out the breach?

[mongoosw1313]

K i just got my impulse and i take one shot at about 160-180 psi and the bolt stays forward and air leaks out the breach but at a low psi like 100-120 it doesnt do it. I have no idea what to do i just got it today so bare with me.

usually u should run 150 psi and under. i run mine around 110-120! Hope that helps!

in your sig it says you own an ion......but anyways, at 100-120 psi it's probably not making a full cycle, which is why the bolt isn't sticking. i'd recommend a tapeworm and an delrin bolt.

If you are dry firing, then you are just getting bolt stick. A tapeworm will help to prevent this. You could just hold a rag over the barrel to give it some back-pressure. Imps with the stock valve should be set at 170-180psi and adjust the dwell for fps. Running at lower pressure will require a higher dwell and use more air.
