Have a friend with a Colt Heavy Barrel model. The gun only operates as a bolt-action. It will fire a shot but will not cycle. If the charging handle is used, it will extract the old round and load up another for firing.
Obviously the problem is somewhere in the gas system; but where?
I haven't been able to look at the weapon personally. I have recommended he check the key on the bolt carrier for any obstruction. He did and claims it is clean; but I am not sure he understood the directions 100%.
If the key is OK, then it seems that the gas tube is most likely blocked or bent and needs to be replaced. I haven't worked on Colts before and have some limited experience on mil-spec AR-15s from Oly, Bushmaster, PWA...
The Colt has a solid pin instead of a roll pin holding the gas tube in. I am told that removing the gas tube in general is a chore and especially so on the Colt. Is this something that can be done by anyone who knows their way around an AR or is this better to send back to Colt and hope that he gets it back before his hair turns gray?
