    According to what I found the in line reg they offer is only 0-450. None of my mags operate at less than 600+

    Also, my uncle in law operates a metal fabricating place here in town. I don't think he does this type of machining, but he may have metal scraps laying around. If you can't find what you need, give me an exact description and I may be able to get it from him.
    I don't currently have the ability to do an allen key hole. I've done a knurled end you can remove by hand, or a hex end you can remove with a crescent wrench... I suppose if I made it a little deeper I could drill and tap the back to 1/8npt and the side to 10-32 so it could be removed that way. I just wish I had the two caps I made... dumb move selling the whole project

    As for input pressure, that's 600 input to the marker when it has the valve back / regulator installed.

      I'll probably old off on the guage hole. I want to try it without it first, if I think I need one later, it should be pretty easy to tap it. I would prefer the 10-32 hole vs the hex end. If you are up for doing it, send me a PM with a price.

      I get you on the pressure. You're saying it takes >600 input to reset everything with the back reg on, but the reg isn't actually putting out that much pressure to fire. I just want to be sure before I plunk down $50-75 on a reg that I find later doesn't work.

        You have to be careful when capping an X-valve. It has feedback from the chamber to the regulator piston. A cap similar to the classic, would cause the air to bypass the on-off pin. You need to provide a plug for the hole where the air feeds back to the rear section of the valve.
        Except for the Automag in front, its usually the man behind the equipment that counts.

          I'm capping a Classic so this shouldn't be an issue right?

            Classic valves are not a problem. The only air passage into the front chamber is through the hole at the top of the on-off pin.

              So when capping this off, do I remove the valve pin? How exactly does this work?

                Remove all the guts. You are essentially allowing the air to go directly from the valve input to the top of the on-off pin.

                  PM'd you Frizzle. Let me know if you can or can't make the cap. Not in a huge hurry, but if you can't/don't want to do it, I need to find someone that will.

                    Anybody else willing/capable of making one of these? Can't seem to get a commitment from anyone.

                      Someone made a bunch of caps over on MCB. I'm trying to dredge up the post now.

                        Never mind, I guess it was Deus. Does he not have anymore?

                          I have PM'd and emailed him but he isn't replying, so I assume he is sold out. I have posted up on MCB as well, so maybe someone will come up with something. BigEvil suggested Coolhand. If any other takers, let me know.

                            Deus finally came back and said he had a couple on stock. I also would like to mention that XM15 said he can make these for $25.00/pc if anyone else is interested. Coolhand also said he is capable, but did not give a price.

                              This thread has peaked my curiousity. Can anyone tell me the benefits of doing this mod, if any?

                                Benefit is in the eye of the beholder. Seriously, I was just looking for something different. I planned on using a foregrip anyways, so figured why not just use a reg in it's place and sheer some weight off of the valve. I also plan on cutting down the rail to match and maybe having Luke ULE the rail after he has pump milled it.
