Comparing marks on feed ramps
I've only put about 75 rounds through my new 6920 and I have a question about the way its feed ramps look compared to my BM's.
My 6920's feed ramps now have tiny "scuff" marks on them. They're sort of rust colored... (We all know it's not rust.)
Maybe it's the brass wearing off on them or something. It doesn't really matter.
Here's the thing, normally I'd say, "Yeah, ok, so what?" But my Bushmaster's ramps--which have seen roughly 800 rounds--are completely free of marks.
