    The only way to test is use ammo in other guns, then start swapping parts, which I do not think I should have to do on a new factory rifle.

    I understand there can be a bad anything from the best company in the world. What seperates great companies from good ones is customer service. BCM was fast to respond the first time and test the bolt, but I have not been able to get a response since then. There solution is to use Quality NATO spec 556. They must be 100% sure it is not a chamber issue, without testing it ??

    Based on some feedback I can agree the Indy ammo may be an issue, but the WWB 556 and Lake City also?? I know may people that are able to run just about anything. So if it is a chamber issue, why not with all ammo. In any case I have been able to shoot Federal XM193 with no issues at all. So BCM may be right after all.

    The reason I bought the BCM was because all of the positive feed back on quality and customer service, I do not feel I am getting now.

    I guess it is up to me to prove there is an issue with their rifle, it is not up to them to prove there is not. They have access to more BCM parts than I do. I guess it it up to me to do a complete test and troubleshooting. I will, and I will post results and the ultimate outcome.

    I am really disappointed and was planning on doing some quality shooting this weekend, not trying to troubleshoot a rifle from a top teir company.

    Thanks again for all the responses!

    I have two rifles with BCM barrels and BCM bolts. Both will shoot anything I put in them. I have occasional failure to lock back with some lower-powered ammo, easily solved with a lighter buffer.

    Looks like it's too bad they didn't test with other commonly available quality ammo. In .223 for example. Looks like they would have found that the gun doesn't run correctly. I don't buy the argument "only run 5.56 ammo in your gun and it will be fine". I wouldn't buy an AR15 with those kinds of restrictions or disclaimers.

    So, is it possible that the higher pressures of 5.56 could overcome a tight chamber whereas the lower pressures of .223 would not?

    From what I've read, they test with an assortment of different rounds including some high pressure rounds.

    Your gun SHOULD run with Winchester .223 (or most other quality .223 manufacturers).

    Yeah, I don't know. Maybe Grant knows.

    Using a new BCG isn't going to tell you anything. You need to isolate it to its' smallest group. Since we are talking about extraction issues we need to look at the bolt and or chamber.

    I knew someone who had this same problem and his issue ended up being an over gassed rifle.

    I see know reason why your rifle shouldn't be able to shoot good quality 223. A have a BCM upper that has so far ran at least 10 different kinds of ammo. Right now, it has a H2 buffer and a Blue Sprinco Spring and it will cycle Tula steel perfectly.

    When we talk about Independence ammo we are talking about Federal/Independence,correct? I was under the impression that ammo was factory loaded?

    From Midway USA's webiste:

    Product Information

    Independence Ammunition is loaded to military specifications by one of the best known Israel ammunition manufacturers, who loads ammunition for the Israel Defense Forces. This round was manufactured to give the AR-15 enthusiast a great choice for an affordable round for target shooting, training and practice. This ammunition is new production, non-corrosive, in boxer-primed, reloadable brass cases.

    Please Note:While the 5.56x45mm NATO and .223 Remington are interchangeable, the 5.56 is a military round that runs at higher pressures than its .223 counterpart.

    It is. Independence is Israel 5.56 and it's actually pretty decent. I've never had a problem with it.

    And for the record before I am accused of hating on BCM- most of my AR's are built off of BCM stuff to include 2 of my SBR uppers.

    For what it is worth, my BCM (14.5 mid) factory rifle would not consistently extract cheap ammo (Wolf, Tula, Silver Bear maybe) for the first couple hundred rounds. Changed to XM193 (Federal) and increased amount of lube (FrogLube), after 200-300 rounds it now shoots any ammo i feed it with 0 issues. (2k rounds later).


    My rifle would do the same thing. Lock bolt back, but fail to extract. Would also extract by hand from mags.
