    My new Colt LE6920 - Are these issues to be concerned about?

    I'm a little bit of a noob when it comes to AR 15's. Got this new colt...about 500 rounds through it. Picture one...notice the small dend/scratch on the right side of the hammer. Picture number 2, notice the paint gone on the inside of the upper....doen't feel rough or anything but looks like something scratched off the finish. Picture number 3....notice I'm shaving a bit of brass...notice the slightly messed up area on the bottom of the case...this is what all brands of ammo look like in both 556 and 223. Never any failures....heard this kind of thing can be buffer tube or pressure/timing problems.....but should I be concerned? Thanks.

    Pic #1 -- Not sure. If it's a true gouge, I'd keep and eye on it, as it could lead to early failure. If it's just a scratch, I wouldn't worry about it. You can always pick up a spare hammer to keep around, just in case (spare parts are cheap)...

    Pic #2 -- This is just the start. The shiny streaks inside the receiver will tell you where you need lube...

    Pic #3 -- That ding is pretty common. Consensus is it's from the bolt lug "wiping" across the case as it strips the round from the magazine and chambers it...

    Most importantly...shoot it and enjoy it!

    Merry Christmas!

    A spare parts kit can and WILL be your best friend. Pick one up when you can.

    I agree with danco above. Keeping your AR in top shape will keep you sending brass flying to the right for a long time. Keep it clean and lubed without overkill, keep an eye on the hammer, get that kit and keep the pig fed.

    I think the hammer is fine, the wear inside the receiver is normal, like was already posted you know where to lube it now. Spare parts kit is a good idea, but mainly for spare springs, piston rings, and the firing pin cotter pin.
    And welcome to the forum.

    So the case head swipe. You're sure it's nothing to worry about? what about the fact the primer seems a little squished. Could this level of pressure issue be of concern? I know not all ar's do this...is there a way to fix it? Is it the buffer tube that needs weight to change timing? Why would a new colt do this if not all do it?

    I haven't shot my 6940 and probably will never shoot it but I already found a tiny ding inside receiver. Am puzzled how it got there as the bolt going in and out never touches it. Does yours have dings inside the receiver anywhere?

    Run that bad boy.
    Put a couple thousand thru it and have another look.
    I would bet you are seein' normal break-in wear.
    Run it.

    Just picked up a 6920 today myself...do you have a part number for that kit? Sounds like something I may need to acquire myself

    Best advice I can give you on an AR is to sit down and write your congressmen and tell them to stop the AWB or you won't have that baby long enough to break it in. Do it NOW.
