I took my DPMS 5.56 14.5" carbine rifle apart that Ive had about 5 years. after cleaaning everything up I noticed that the flat sides of the gas key has removed quite a bit of material from where it rides. there where patterns in the bolt carrier bore look good and smooth in my opinion.
My question is, is this normal after at least 10k rounds. Im going to a mid length gas system to see if it helps. any other ideas whats going on.
Thank you.
