    Quarter circle 10 AR-9 ejector loose?

    I was just talking with a buddy of mine at work. He has a QC10 lower mated to a PSA upper. He says he gets CONSTANT stovepipes. He noticed the ejector pin on the lower behind the magwell is loose. He thought that was odd. They say its normal for theirs to have play. Every one I've seen they are pinned in and very stable with no play.

    He has tried various ammo brands and its pretty consistent across brands.

    Can anyone with a QC10 9mm verify that their ejector pin is also loose? Any other suggestions? He was thinking it could be something to do with an incompatibility with his bolt and maybe needs to replace it with a QC10 bolt since those are designed specifically to interact with that sloppy pin. Or should that pin even be sloppy?

    The circled ejector is wobbly and not tight. (not the upper/lower pins)

    This is the set of pins inside the lower that secure the ejector pin to the lower. Not the pins that connect the upper and lower together.
