    I use the O-ring in my BCGs. Is there a specific reason you don't like them? Just curious. I was just always told that they help with extractor tension on the carbine length gas system but they're not really necessary for the mid-length guns.
    Only hits count......you can not miss fast enough to catch up

    I'm using the carrier and changed the bolt out with a spare(tested) one i already had.

    Other than staking(which was obviously good here) are carriers from "lesser" manufacturers known for issues?

    I cant recall hearing of any.

    Everything I have heard is that it's the bolt that is more likely to fail, however, I'm sure that the carrier could fail as well. I personally have seen 3 lower tier bolts fail in various conditions, from a training class to bench shooting. Two DPMS and one RRA.

    Others with more knowledge will chime in I'm sure.

    Yeah,the bolt is riding in one of my MIADs for now.It'll probably get demoted to a range bag eventually.

    I was thinking(hoping) the properly staked M16 carrier would be gtg.

    Too much extractor tension can cause problems just like too little extractor tension.
    Bravo Company clearly states that they're not necessary, but their customers want them so that's why you'll find them with their bolt groups. (included with them, but NOT installed)

    I wouldn't trust a gun that needed an o ring to extract reliably. I have plenty of carbeans, including 2 sbrs that run fine without them. And I'm very reluctant to ever put anything in a gun that wasn't part of its design.

    Looks like they're in stock again.

    Got mine today.

    I can't find any kind of markings at all on the bolt. Maybe I'm blind but it looks 'sterile' to me.

    The BC has nice staking, of course. Mine has a noticeable blemish on the side. It's actually more noticeable in person than in photos: it has a bit more depth than I was able to capture in image. Doesn't really bother me, but figure it's worth a mention.

    That blemish is actually where a manufacturers mark was ground off. I have seen a ton of M16 bolt carriers with that and I have one sitting on the table here with the same thing on it.

    Oh, interesting! Thanks for the info: I did not realize (obviously, ha).

    As a potentially stupid follow-up question, under what circumstances will a dealer usually take markings off of a product? I.E. are they surplus parts that the original maker doesn't want to be associated with? Factory seconds from someone? Extra contract parts?

    I've never purchased parts that had such a thing so I'm not familiar with the backstory on such a practice.

    Mine has the same grinding off mark. At first I was a little bit worried (is that a weak point?) but then I figured Grant would not have sold a part that was flawed in a way that made it less reliable. Glad to hear I was right!
