I know some wear is normal to this area, but I thought it was usually confined to the area of the cut-out nearest the buffer tube. I have this wear, but also some more that I was curious about. Pretty sure it falls under the "within normal tolerances--shut up and shoot it!" category, but wanted to ask regardless.
Rifle is a 14.5" midlength w/SB, fired with 62gr 5.56, about 200-275 rounds so far.
