Need mag help

[BIG BOB]

Long story short I have this mag in my possession and dont know anything about it. I aired it up with a standard 750psi tank and it has enough pressure to push the trigger out but when I pull it, it just makes a little noise and the trigger kind of goes limp. Included are pictures of what I have for it. So any input on what to do would be greatly appreciated.

That pack of orings doesn't look too fresh. :)

RT pro valve? Looks nice.

That's a level 10 bolt you have there and is likely to be part of your problem. To get it working, I would take that long bolt spring off and use the gold spring. Make sure you have a little oil on the bolt stem and see if it slides in to the bumper pretty smooth. If it is stiff (like you have to pull more that a little to get it to fall off), you're going to have to tune the level 10 in the power tube. If it slides pretty well, just put the lighter spring on there and give it a few drops on oil in the asa and see if you can get it moving again.

If the unused urethane orings look old, I wouldn't pull the ones on the valve out until you have some in hand.

There's a level 10 video on you tube as well as a lot of tips on the tech forum.

The trigger rod on your sear looks like it has some white tape on it. When you get air pressure on the trigger, check that you have about a credit cards thickness gap between the rod and the back of the trigger when it's hanging down or you are pushing it forward. It needs a little slack there.

Turn up your velocity.
Use oil (autolube or gold cup).
What tank are you using? (pic would help)

I changed out the spring and oiled it now the gun will pressurize and fire one shot and not reset. I also turned up the reg (allen screw in the back) quit a bit and nothing seemed to change. What else should I try?

Thanks for the help so far

So I followed the lv 10 installation and noticed the back washer was missing so I installed everything correctly according to the directions and now it wont fire.

I have like 10 carriers, are there any differences between them?

I have 2 shims in there now, should I add some or take some out? I put the middle spring on it instead of the gold one. My tank only has about 500 psi in it at the moment so that might be the reason.

No shims at first
You will need to refill your tank. RT valves need more than 600 psi minimum.
Quick tuning instructions:

Remove all LVL 10 shims.
Pick 1 carrier o-ring and stick with it.
Use oil.
Use #2 carrier (2 lines, no dots, or largest one you have).
Shoot 1000 shots to break in o-ring.
Move broken-in o-ring to largest carrier that doesn't leak.
Use red spring for 285 fps. Use longer spring for higher velocity or to be more gentle (fragile paint), shorter spring for lower velocity or to be less gentle (thicker shell).
If bolt sticks after encountering a jam, add a shim.

Low tank pressure is your current problem, you need atleast about 800 psi for it to cycle.

If you order any parts in the future, get a clear urethane bumper instead of the blue one. They are softer for the level 10 bolt. It's not a problem right now.
