So I just got a G-1 for Christmas and I have no experience with the gun at all. I read the manual, I watched youtube videos... I did exactly what everyone explains to do. See, when I got the marker and checked it out, the foregrip was... loose. It wiggled. I didn't think anything of it, but later I got home and decided to check the marker out more thoroughly.
I wanted to change the feedneck. However, I had no idea that changing the feedneck meant totally dismantling the gun. I thought it was a simple process but it wasn't... Either way I carried on, following the instructions of a few youtube videos and the manual. Everything goes fine until I get to the point where I need to unscrew the foregrip(I guess the regulator?). I turn and turn and turn and nothing happens. It doesn't tighten, it doesn't loosen. It just spins and spins. Am I doing something wrong? Is my G-1 messed up? I'm hoping I'm just missing some very simple step, but I suppose at this point if I can catch it early that my marker is messed up I can just return it/contact support.
Shouldnt be messed up. There may be a couple causes. If you do want to get the reg off without unscrewing it, take the barrel off, take the grip frame screws off, and put the allen key through the top of the shroud and unscrew the small set screw. This should disengage the reg from the marker body/breech. From there you can try to unscrew the reg from the vertical asa.
The second option you can do is screw the small set screw in the reg grip so it can grip the reg sides a bit more. The problem with this is that it is fairly easy to strip the small set screw, and may make the problem worse. I would not go this route.
The last thing you can do, which is highly reccommended, is to get a set of $5 snap ring pliers. File them down to fit the holes in the snap ring on the reg (dont need any "special snap ring pliers" - hogwash). Take off the snap ring. Slide off the swivel, unscrew the set screw, slide off the reg grip, then try unscrewing the reg directly. It should come off fairly easily with direct torque from your hand.
Seems like it was screwed on too tight or the threads ceased or the grip set screw wasnt tightened from factory (which isnt a big deal). Once you loosen the reg up, put some lube on the reg threads and do not overtighten. Just until snug. When you put on the set screw, do the same. Not overtight, but snug, or just past that. You will be able to twist the reg normally using the grip after you lube it.
Hope this helps. If you need any other help, just give me a shout.
Edit: Dont do choice #1. If your marker is brand new you might want to do option #2 but be gentle. Tighten the small set screw until snug or just past it. If you find that its "scraping", just stop and go to option 3. You will need snap ring pliers anyways to service the reg.
