    Gas Ring Replacement Question

    Ok so this is a really stupid question-

    Apparently my rifle just busted a gas ring- one of the little tips broke off, for the life of me I don't know how and I would never have noticed if I hadn't been cleaning it the other day...

    So I need to stick a new one on.
    I have a set of replacement rings fromBCM's rebuild kit.

    Dumb question- do I need to replace ALL the rings, or just the busted one?
    Rifle's only got 12-15-hundred rounds through it, but I'm tempted to treat them all as suspect givent the nature of the failure and yank them all off.

    Short answer, yes, they should be replaced in sets.

    Correct. They should be replaced in their entirety.

    I'm seriously considering it. Especially after this time- was a real bitch to clean after letting it sit for weeks after the last range seesion (see, I'm already that lazy about cleaning), plus a bunch of mud in the chamber from a mag I dropped into said mud than had the brilliant idea to try and use.

    You know- I wonder if that may have caused it- at the event I was at, I dropped a full mag in the mud (it was raining most of the day) trying (poorly ) to reload in the middle of a drill. Being a timed drill I just grabbed the mag, noticed there was a chunk of mud stuck in it, but stuck it in anyway and popped the bolt release.
    This resulted in a stuck round (yeah, I'm a genius.), and the rifle had to be mortared to get it out.
    I forgot it while the rifle sat in the closet for a while, then took it out to shoot- mud was apparently still in there and I immediately got another stuck round, resulting in a second mortaring.
    Could the round being forced into the chamber, or mortaring have caused the ring to break?

    Bringing this back for a related question. One of my gas rings on my Noveske also broke after only about 1,500 rounds (I think at the same event as OP's...). I know its a very minor fix but it seems like a short service life to me. Is that about normal, or is it likely to have been something else? Not enough lube maybe?

    If that's a response to me, as I stated I realize it isn't a big deal. My reason for asking is because I want to know if maybe it was a symptom of my lube drying out (I'm considering trying a different lube).

    Doubt it had anything to do with your lube preference,although frequent application of lube to the gas rings/bolt tail does help,particularly in regards to keeping the carbon soft.I'd make sure there are no burrs in the carrier bore,replace the gas rings and be happy.
    The gas rings are simply stamped sheet metal.They do fail from time to time and the quality varies greatly from supplier to supplier.Just replace with the best know quality source you can get(and buy a spare set).

    Little tip I try to follow,when intalling the gas rings take note that one side of the rings will have a stamped sharp edge and the other side will be rounded,from stamping process.Install the rings with the sharp edges all pointing in the same direction towards the rear of the bolt.Not anything specific other than to keep the sharp jagged edges from binding on each other until broken in.

    I personally prefer the McFarland type one piece rings as I think they are more robust spring type steel production than the stamped standard rings.(But thats another discussion with varying opinions)In this case the quality(ring diameter) can vary greatly as well,so buy from a known reputable source that checks and/or specifies the ring size....good example, from past personal experience, G&R Tactical and Armalite in that regard.
