Mag won't fire

[XrobX]

Just finished building my mag, got the tank filled and it won't fire. I'm not exactly sure what it could be. Any suggestions?

Post the specs of the mag. It may be several things:
- Velocity adjuster too far out
- tank output too low
- on/off too long

Xvalved mag with inteligrame. I'm running it on a smart parts max flo reg. It's set to about 800.

Check the velocity adjuster first, also your lvX carier and oring.

The velocity was the issue, its working great now, i just have to work out the rest of the other little things with it now. Thanks for the help.

No problem, post if you have any other issues.

How about a sear pin stick?

Do you mean the sear itself is sticking? Or you just can't get the sear pin out of the rail?

[XrobX]

The pin itself if sticking. When I fire it now the pin will stick after a few shots. After pulling the trigger a couple times it will come loose but will stick again after a few more shots. It is happening quite frequently now.

if the pin sticks would it not let the bolt come all the way back?
cause my mag just when i pull the trigger shoots but when i let go it shoots again and the bolt doesnt go all the way back. its like my 68 classic mag has a response trigger. lol

its possible the rail im thinking

Fiddle with your field strip screw. Loosen it up pretty well and then just tighten it hand tight. If it's too tight or loose it can cause bindage.

Ill give that a shot. thanks.

hand tightening it caused it to leak down the barrel.

You are getting bolt stick. It is usually a powertube related issue due to a carrier that is too tight. If the field strip screw causes changed in the leak or sticking, then perhaps the pim on the bottom of the body is too long and is causing the body to not sit tight against the rail.
