Mine are the same way. I believe some solder the tube to add rigidity. I was planning on trying this but have not looked into it too much yet. Hope you get some good response! I'll be watching.

Look for a small retaining cross-pin that goes on the underside of the gas block where tube meets internal threads.
Silver Solder is a solution. Make sure you're on straight.

Thanks for the responses ,Ted checked to make sure retaining pin was there, tube seems to move more than it should, gas piston mic's .429.5, might try a new retaining pin. Thanks Rick G.

I took (I think Dan at VOWs') advice and 'tinned' the tube. I used a lower melting silver solder. None on the threads; jammed in tight, pinned. still moves but very little. Haven't tested waiting on LS.

Mine moves a lot too. The retaining pin was a punk to remove so I believe that the tube pin fit is ok. I will try loctite first, if that doesn't work, I'll try the silver solder. I guess as long as there is no major gas leak, the losseness is no gig deal? Still waiting on receivers as well.
Good weekend to all, :cool:

My G1 kit as well as my Imbel kit and M444 all have loose tubes. The M444 shot like a dream from the box and continues to do so. Hope the looseness isn't a big deal!

I've got a L1A1 barrel that acually has gas
erosion below the tube from a loose fitting
tube and the tube threads were badly eroded
also.Keep the tubes as tight as possible and
everything will last much longer.
