    M11 Nine, wear/marks on barrel right where it sets above trip

    Is this wear on the underside of the barrel (right where it rides above the sear) out of the norm? I believe it is normal as I have 2 m11s, (a 1985 and a 1986) and they both have the exact same wear in the exact same spot, but can you all confirm for me?

    Photo below shows both uppers side by side. The 86 (on the left) has only had a few mags thru it, so less pronounced, but in the exact same spot.

    All of my MACs have those marks due to the sear contacting the barrel. It's normal and self-limiting.
