I go to take the trijicon picatinny mount off a 508t x2 and noticed it’s getting hung up slightly on the front lug. Comes free with minimal effort, but when I get it off, it looks like fine powder on the lug. Weird.
I look at the where the lug goes into the optic and there’s more of the powder in the recess, and a little oddly-shaped hole. Wtf? The lug feels tight in the recess, with no slop. So I don’t think it was vibrating and wearing a hole in the recess. Ever seen this? I’m stumped
