    Thay don't always tell you what they did to service your gun. Give 'em a chance and run it when it comes back. You might be suprised.

    A while back I took two new BCM uppers to the range. One 20" & one 16" middy. I lubed up the bolt assy on the 16" with Slip 2000. The 20" was dry (forgot to lube it). The 16" ran Wolf 100%. The 20" choked on Wolf every third or so round. Next time out I lubed the 20" well & no problems cycling Wolf. My $.02.

    That has been my experience as well.

    If quality is adherence to requirements, how is it not a quality firearm if it doesn't function well with ammunition it wasn't designed for? Keep in mind that the M16 FOW does not have an adjustable gas system to ensure reliable function with a multitude of different ammunition types. This is where commercial "overgassed" barrels/gas port sizing comes from (Is it "overgassed" or of poor quality for not meeting TDP specs if it was intended to run lower pressure ammunition?) . Your choice in upper receiver and buffer selection should absolutely be driven by the ammunition that you choose to fire... until a hard use adjustable gas system is designed and introduced for the platform. Somebody work on that; Noveske, you're halfway there...

    I've been working so I have not had the chance to take the rifle out yet but I will be for sure sometime this week. I'll probably try a few boxes of Wolff and see if I can replicate any of my previous malfunctions but otherwise I don't plan to shoot it too much, least not for a while.

    I'll definitely keep this in mind. I generally do keep it pretty well lubed but I'm going to soak it the next time I'm taking it out.

I am having the same issue that you are - relatively new BCM 14.5" lightweight upper that feeds IMI 193 flawlessly, but has constant failure to feed malfunctions with Wolf WPA that sound identical to yours. I run a carbine buffer exclusively with this setup, and feel that I should be able to fire Wolf. I'm going to follow in your footsteps and contact BCM if they did something that fixed your issue.
    I'll at least try that carbine buffer again and let you know what happens. The thing is, it's expected out of yours because 14.5" uppers are notorious for this problem but 16" mid-length uppers should not have this issue; at least not to this extent.

    So I finally got the chance to take my rifle out again yesterday for a few minutes. First time since I received it back from BCM.... and... well.. Same old shit.

    First magazine was American Eagle 223 brass. About 10 rounds in, it went click. I pulled the trigger again and it went bang. Light primer strike? Who knows. I'm not discounting anything with this rifle, at this point.

    Second magazine was the same 223 - functioned fine.

    Third magazine I loaded up the Wolf steel casing. Within about 5 rounds, I suffered the same malfunction that's been plaguing me since I assembled this carbine. The round makes it about half way before the BCG slammed closed on it. I cleared this malfunction by hitting the back of my stock and manipulating the charging handle. There was obviously visible dents on the round from the BCG. The bolt did not lock back after emptying this magazine.

    Afterwards, I did some testing with the 1 round in each mag to see if the bolt would lock back. It didn't lock back once the whole time when shooting steel cased.

    I had a standard carbine buffer in the whole time and I lubed my upper/bcg generously before heading out and added a bit more lube right before I loaded the Wolf ammo.

    I have e-mailed BCM about this. I'm not particularly happy to see people with identical rifles firing the same exact ammo without issue; meanwhile I encounter on average 1-2 malfunctions per magazine.

    We'll see what happens tomorrow - I'll be shooting strictly XM193 and if that malfunctions again then I'm officially ****ed.

    Sounds like your simply doesn't like steel cased ammo.....

    Your choice now is to keep it and stick to better ammo or replace it.

    Evidently, but the big question is why is mine the only 16" Mid-length BCM in existence that consistently chokes on it? This isn't normal. If I had a 14.5" then I'd understand but that's not the case. At this point I know there is nothing else that can be done but it'll be interesting to see how BCM responds this time around.

    You're not alone ...I know if others. I also know of a few Colt, DD, LMT, etc that won't reliably digest steel cased ammo. I find it to be more of a case by case kinda thing that isn't brand specific.

    You could most likely replace it with another BCM upper of the exact configuration and have no issues at all. Like I said some eat it while others choke.

    I don't know how Wolf compares to Tula, but my BCM 14.5 middy ran 40 rounds of Tula a friend gave me this past week perfectly fine. Standard spring, H buffer, A2X. The majority of those 40 rounds were in transition drills, and it locked back every time.

    Try running your gun with a good amount of lube.
