    Gone ReTro (& a Q)

    Ok, I'm a little behind the times, with all this X-Valve stuff & all, but, I got a nice deal on a ReTro valve. I set up the LX, popped it into my "Classic" Mag, and began ripping away!

    Now, my question is, what can I do to coax a little faster ROF out of this thing. My input pressure is turned up to 900psi. The on/off measures .752. I know AGD recommends against it, but will trimming the on/off a bit (say, to .740"/.745" to increase the reactivity of the valve?) I'll try a bit more output pressure as well (1000psi)

      I'd recommend against trimming the on/off. You may run into a situation where it's total runaway. I'd up the pressure to 950 and see where we are there. If that doesn't give the desired results, you can try the on/off pin. But I'd say go pressure first.

          I agree with dayspring. Up the pressure and let the valve really break in(assuming it hasnt already). What can also matter is the trigger frame you use. Certain frames have excessive travel in them and can discourage the gun from really taking off(at least in my experience). But just go with a higher input pressure and it should shoot good. good luck

              And beleive me, that's good advice!

              ...while here at work, I decided to trim down the on/off a bit. It's down to .742" right now. It really doesn't seem to shoot any more "reactive", BUT the sear has started to damage the bolt (the edge where the sear contacts it!)

              yes, a new on/off is on order

                  Also shoot lots and lots. I found mine took about 4-5000 shots before the oring started to wear in nicely, and this made a big difference in reactivity.

                  On the on/off pin subject, I trimmed mine down to .740 and have nice reactivity, no runaways, and no bolt problems. I didn't want to increase the input pressure too high (currently at 850) as that effectively limits the useful shots from a tank. Every valve is different though- some need shorter pins, some don't. Buy a couple spare pins if you decide to experiment.
