Not sure of the rifle or the compressor in question. On my Tippman and Ninja bottles I have a regulator, one at 850 psi and the other at 1600... with this fill station.If you want to "shock" it to seat the valves, why not hook your compressor up to the gun with the valves closed, start the compressor and let it "Dead Head" to the 3000psi then quickly open the valve?Maybe I am missing something.
