    It is missing the point to think that the martial art is solely in cutting a man down; it is in killing evil. It is in the strategem of killing the evil of one man and giving life to ten thousand -Yagyu Munemori

    I think you meant ejector spring

    I'll just assume you were referring to me. I did read the thread and it seemed to me that the original question got lost. I understood the original question to be an examination of how other manufacturer's methods compared to BCM's seemingly ideal 16" Mid Length Gas System.

    When it turned into yet another debate on ejection patterns - I thought I'd make a feeble attempt to try and get the thread back on track. My point was that ejection patterns in todays AR/M4 market are just not that relevant. If the gun runs then it runs. I'm not sure that running 'well' can really be qualified.

    I'll just leave the thread management to the mods and lurk like I mostly did for the past four years. My bad. Carry on.

    Damnit. Yes, you're right. ejector, extractor, it all gets muddled some times.

    No, actually I wasn't.

    Depends on how you like to take care of your weapon or not.

    If the gun runs then it runs. I'm not sure that running 'well' can really be qualified.
    It absolutly can. It is best expressed by bolt speed and ejection pattern over time can be a great indicator. Under most circumstances, all ejection pattern tells me is when it's best time to change my springs to keep the gun in optimal running condition (i.e. "well"), but, over time as spring maintinence starts having less corrective effect, I know that a bigger issue is developing elsewhere and I need to keep an eye on it. As in if I know i've got 11k rounds down the pipe, and have done regular spring maintinence and my ejection pattern is shifting more and more forward, even with new springs in critical areas, i'm pretty sure my barrels gas port is getting too large and the barrel is getting close to the end of its service life.

    Like i've been trying to say, ejection is a secondary performance indicator of the overall health of the machine. Treat as needed. Take a new ejector spring and a new action spring and call me in the morning if it's acting overgassed. If it's acting undergassed all of a sudden, I pull the carrier and start checking the carrier key first, extractor spring next, buffer, spring, and tube for fouling next, etc. etc.

    It's sort of like a mechanic being able to tell you what's wrong with your car by the squeaks and thumps the car makes when it's running. Sure the car is running, but it's not running "well".

    I'll just leave the thread management to the mods and lurk like I mostly did for the past four years. My bad. Carry on.
    To each their own.

    Just didn't want you heading out thinking that I was busting your balls when I wasn't.

    Oh yes, twice actually since your comment seems directed to me.

    I also happen to do this as a profession and know better than to use ejection angles as a diagnosis of an AR.

    Grumpy, it'd be helpful if you had some hard data to go with all that anger. Especially helpful would be examples based on your experience (with Noveske) of gas port size + ammunition used + buffer used and results based on aforementioned variables. Quantifying those 3 would be far more helpful than debating ejection patterns and the associated bullshit voodoo.

    For the record, I read the entire thread and didn't see you mention once the port size on that Noveske.

    Ran an H2 buffer in it and it didn't help much. Putting a Vltor A5 with a Wolff extra power spring brought it down to"normal" function.
    Again...port size, ammo used? 'Normal' function as defined by you is what, casings landing at ___ o'clock every time?

    That's nice.

    I've been doing this AR thing for a few years myself and know a thing or two about how they work as well.
