    Lmfao. They are staked. That is a sign of properly installed screws. They aren't meant to come out.

    Different makers have slightly different methods of staking the screws. Do a quick google image search, you'll understand.
    Maybe send an email or 2 complaining about their method, Im pretty sure you wont hear them laughing thru the email.

    I can't see anything. Are you referring to the line on the side of the gas key?
    From the blurry Pics it doesn't appear to be deep.
    I'd take a look at the chamber and see if there is a burr or something.

    I checked all thru the upper no burrs in it.

    But in the 3rd pic where the stake impressions are next to the key screws on the left side u can see it the best the gouges r down to bare metal on one of them and are bigger on that side.

    Its the old bcg original to the rifle anyway just keeping it for back up I have a better one in it now (PSA) so not a big deal was just curious if anyone had seen anything like it.

    All Im seeing are the stakes. Thats how Colt does theirs, as well as a few others. RRA and CMMG (at least) does it a little different.
    Maybe we just arent seeing what youre talking about. How bout a clear pic? And maybe edit the pic with an arrow pointing to what youre talking about.

    Are you talking about the wear along the side of the gas key on top of the carrier?

    I did some quick photo editing. Are you referring to the big circle or the little one?

    The small circle is proper staking, some times it is even staked all down the side of the key too. The big circle could be a couple of things. Like they said, a burr, or you're upper receiver and or carrier are out of spec. The last thing could just be poor quality carrier coating.

    They just look like good stakes to me. Hard to tell from the blurry pics but they look like my BCM BCG stakes do.

    Since staking is a method if displacing metal, there will be variations if where that metal gets displaced to. Some will go up, some will go in, and some will go out around the sides. The displaced metal is behind the higher tube of the gas key and is not likely to scratch or mar the receiver.

    If you are concerned about sharp edges cutting you while cleaning, or just snagging then you can take a fine file and dehorn the sharp edge a bit.

    Thanks for the help appreciate it just haven't seen any others like it probably just how they stake it but seemed very odd compared to what I have seen.

    Looks like a really good hand staking job. The bigger name (Colt, BCM, DD) use a device similar to a MOAKS which makes the staking much more uniform and pretty.
