Gas tube does not need cleaning. Book shows to clean the carrier key with a pipe cleaner but I have never done it and never needed to. The only time I saw a gas block get clogged was from shooting a 22 kit in a machinegun over a period of time. Could check the carrier key and screws to see if they have become loose.

As j3 said check that carrier key and it's screws. I have seen them even come loose when they were staked with a punch. Also check the rings to be sure the gaps are not lined up. If your bolt will fall out of the carrier by it's own weight, the rings need replaced.
My orginal Colt 6601 (1989) is now on its third barrel. I am guessing 14000 + rounds. I never cleaned the gas tube. Ha, I running the same rings too! I have heard or read somewhere that laquered cases from Wolf ammo can cause gas tube problems but that is hear say and never seen it first hand. Dave McGrath |

Shameful bump. Carrier key loose very weak stake job. Anyone got a link to proper staking method? Are there any little gremlins that will jump out at me if I remove key for cleaning? I will remove bolt and let it soak while at work today. I thought since it's about to fall off anyway why not clean it. Thanks for input.

No gremlins. They say to replace the screws. Link to manual below that has staking methods in it. Also a link to what Armalite says about how to tighten them.

Sir; It is to my understanding that any amount of gas loss can be reason for malfunctions as jcncc is having. Per TM 05538C-23&P/2 U.S. Marine Corps Technical Manual 3-18 (quote) Note: Make certain ring gaps are staggered to prevent loss of gas pressure. Several years ago I attended the Small Arms Firing School conducted by the Army Marsksmanship Unit at Camp Perry, Ohio. The instructors stressed this same procedure as to prevent gas related malfunctions. Dave McGrath |

Ring alignment really does not matter much.

bad information has no shelf life and there is no known way to curtail it short of repeating correct information at every chance. test my statement for yourself. ARs will work with ONE gas ring. although I already knew this from extensive experience it was also taught at the COLT Armorer's class I attended a couple years ago. if a rifle already has marginal function then gas rings could contribute to short recoil but in that case the problem is not the gas rings but instead the marginal function.
