    Just got home from work and found my CMT full-auto BCG waiting on me. Looks to be good quality. The staking leaves a little to be desired. And in spite of the email from the company, it is MP marked. I'll have a range report next weekend :supergrin:

    Definitely a bit weak on the staking.

    I ran AR-15's for decades before staking ever became an issue. I know others who have done the same. The myth about the gas key coming loose is just that, myth. Unless you break the seal and loosen it, and reseat it, it will be fine. Or, you could use a hammer and nail set or chisel to enhance what you have.

    Just stay away from N Dallas and you'll be fine.

    Agreed.

    You could go and booger it up so badly that it'd be considered "staked" (or better yet, simply locked in place).

    Run it and keep an eye on it. I still doubt that you'll see any problems outta it. :wavey:

    Gas keys coming loose are a low frequency event, but it happens and when it does is usually mucks things up pretty good. More than anything, poor staking is a glaring sign of poor quality control that we can easily see. If poor staking was missed by the qc guy, what else got missed that we cannot see?

    Two words: CALL. JOHN.

    Exactly. Staking should just be an insurance policy on a quality bolt, as it would be properly torqued with the right fasteners to begin with. However, in the event that it wasn't done exactly to spec, that staking can (potentially) be the only thing that keeps your gun from going TU.

    Don't worry about it. Run it and if the gas key comes loose deal with the problem then.

    Should be fine.

    While it's not a perfect job, there is more than enough material
    displaced. Lube it up and shoot the darn thing! :cool:

    That was a nice way of saying 'stupid BS internet liars spew'.

    I had ~15k rounds through my first AR and another 9k through my second before this term started floating around the internet.

    I started asking people at my club about it, and I couldn't find anyone who had problems from "improper staking" or even knew WTF it was. These are people I know shoot a lot, because they keep me in brass.

    If you think about it, when did the term start floating? About the time "The Chart" popped up on M4Carbine.net.

    "Real world shooters" as Bren would say, that I KNOW shoot the snot out of rifles, never had any problems with the gas key. Internet know-it-alls desperately seeking validation seem to have all kinds of problems with it.

    When I hear some twit on the internet using "proper staking" as validation for spending twice as much for a rifle, and nobody I know has even heard of it...... I tend to believe the people I actually see shooting.

    It's just one of those items "The Chart" lists as being on "top tier" rifles, and a subject the kids use for validation.

    Now if someone takes their gas key off, I can see where they would want to stake it. I don't break mine down that far. Otherwise, I don't know any mature shooter off the internet who is even interested in the subject.

    And oddly enough, my BCM isn't much better staked than the OP's CMT. If I was one of the internet know-it-alls seeking validation, the staking job on my BCM wouldn't be good enough. Hell, I had to look twice. I would have thought it was much more heavily staked than it is. That also makes me think it's an overblown issue.

    Dude you have no clue,...........been shooting the platform
    for 27 years. Seen it many times, but on hard use military
    weapons, not range plinkers. Get an idea who you are talking
    to before you start spewing BS you pulled out of your arse! :wavey:

    I don't believe it.

    ETA: maybe so on military weapons where the armorers break them down completely. And maybe even with plinkers people take the gas key off of.

    Other than those times that are caused, it's BS. ETA again: It's lying, stupid BS.

    You don't like being wrong, or exposed as a liar, do you?

    I say again: for the everyday shooter, staking is NOT a problem.

    I don't give advice. I just provide feedback from experience. I don't "recommend" anything to anyone, like some of the self proclaimed gurus here, because I don't consider myself an expert. Nor do I need to be seen as an expert. But I do have years of experience and thousands of rounds behind me.

    When liars make up BS in order to feel like a guru, I merely express an differing opinion based on my experience. And I don't see that as advice. If someone wants to buy a brand I don't like, or that I don't own, it doesn't bother me. I'm just glad they are buying. Welcome aboard.......

    Maybe I've misjudged some of these internet know-it-alls. Maybe it's not validation in their brand loyalty they seek, as much as "guru" status. Maybe they have a need to feel important, and changing\guiding the purchases of others makes them feel important.

    Maybe they spew stupid BS from the chart, because they think it makes them appear knowledgeable, instead of just trying to make people buy the brand of rifle they own. Definitely something for me to consider.

    Until I run across someone in the real world who actually has had gas key issues due to improper staking, it's still a big fat lie, told by liars on the internet who are seeking validation and\or guru status.

    I do not seek guru status. If people want to buy a Stag\Bushmaster\RRA, I say 'I hope you get years of enjoyment out of it', which is the difference between me, and some of these guru wannabes.

    And yes, I've been drinking.
