I bottomed out my opr/lpr. Than i aired and the psi does not move from 300... I was turning the opr in and out but the psi doesnt change. Than air from the opr just burst out and the psi went back to 0... wtf did i do.
Theoretically you should be able to set your regs and leave them. If they change their set point upon being aired up then there's something wrong with the reg. It should hit the same set point every time the air into the gun is cycled. Other wise the consistency of the reg output won't be there and the chance of drop off/shootdown will be there.
Another point is that the LPR should be consistent and the velocity should be adjusted by the HPR. If the LPR is low then the chance of FSDO and drop off/shootdown is pretty great. With a consistent LPR the bolt is always moving at the rate so kick/recoil should be about the same regardless of the velocity.
Oh and I added your first post text to the FAQ so it is all in one place and easier to read.
I'm interested in these guns on a couple of different levels. I'm thinking of carrying them in my store, and making new LPR's for them.
Cyborgs are adjusted from the LPR as well. as a matter of fact, you set the hpr to 300, and adjust velocity with the lpr. Made for one of the most consistent guns I have owned. after the borg, I tried to chrono my ego like that. definite no go. just waiting for my LE fusion in the mail. then i get to have all the fun of figuring this new gun out. YaY!
what happens when you cannot change the hpr? ive tryed to turn the screw but its way to tight. i do not want to force it because i dont want to hurt the gun but it simply will not turn. gun is set to 275 psi and is still only shooting 260 fps...
I wouldn't say how to chrono a stock fusion because your fps will probably increase at least 10 fps when your wear in your reg. However, this is a great way to adjust your gun temporarily from stock settings. In other words it has to be done no matter what, but you'll have to do it again after the first few tank refills you go through to get your more permanent settings.
