LR308 Free Float 4 Rail Handguard loose

[zabo]

Mine has come loose on my LR-308 24" BB (the rail was factory installed).  For the life of me I cannot  get it tight.  I called DPMS they said it should tighten by hand.  It's as tight as I can get it and my rail still can turn about a 1/2 inch back and forth (it's hitting the gas tube, I think it would probably go all the way around if I took it out).  Can it be tightened without taking the gas return off?  deer season is close so really do not want to send it back to DPMS.  Sorry for my amateur description, i'm new to the AR world. Any idea or help appreciated.

Did it start out tight brother? How about some pics so the guys can help you out a little better. ;)

Can you get us a picture of the rifle/handguard. It'll help for reference when we try to help with a remedy.

On a trip will post some when I return.  Don't think it will help much.  I noticed yesterday I could  actually rotate the barrel also.  i think  I need to remove the gas line to tighten it.  From what I've heard it's a bitch to remove the gas block from the Bull Barrel.  Might just try to find a local gun smith, which sucks sinces it pretty new.

It the tube is tight to the barrel nut, then the barrel nut is what's loose.
