    Fresh Build AR 15

    I just put a new AR15, Anderson upper and lower 223 Wild Barrel M4 18 inch mid-length gas tube
    non-adjustable gas block, together and took it to the range. Has no problems cycling but when I
    looked at the spent cases, they were dented after the neck about 1/8th inch down the case body.

    Any ideas as to what could be wrong?

    Sounds like they're being ejected hard and the cases are hitting the deflector. Which is what the deflector is for. Where is your brass ejecting? 4-6 o'clock? What buffer and weight do you have?

    If the barrel is 12, it is coming straight back at 6 and has left a scrape line on the deflector. I have a carbine buffer (not sure what weight it is), tube and spring. I purchased the butt stock (6 position collapsible) with buffer and spring all together off of ebay.

    Get a H3 buffer. Sounds like the gun is slightly over gassed.

    This.

    I'm guessing you are using a standard buffer spring/buffer. Needs to be heavier. One of the reasons I like gas piston systems now. With a can on I have do dial it back some for this reason.

    I should expand on my answer too....the reason your gun is over gassed, is because the rifle length gas system (12") is designed to work with a A2 buffer. Which is heavier than a standard carbine buffer.

    WYLDE.

    Sorry, but that one bothers me a lot for the reason that Bill is still alive, and you should spell his name correctly.

    Would adjustable gas block help with this problem, of being over gassed?

    Nate, I'm glad you know how to spell his name. I'm sure you have never made a mistake before.

    I haven't been in this field for very long, so give a newbie a break.

    It may. However the buffer is easier to change
