I just got a new AR-15 and i put a couple rounds in the chamber and the case is all scratched up....is this normal? When i put the round in the chamber it really doesnt go in all that smoothly is that normal as well? I'm new to AR's....Thanks for the help..

The scratching of the case is 100% normal. If you are following the charging handle then the rifle might be sluggish or fail to completely chamber the round.

+1 for scratching being normal

ok I figured since it was new that it was normal....Will this continue to do this or will it get better as more rounds i put through the gun?

Also someone said that DPMS barrel are sharper than other companies barrel's is this true?

Thanks again guys

is it just your feed lips from your mag scratching them as they strip off? thats what i usually see happen

Two places rounds get scratched:

Feed lips of the mag

Locking lugs of the barrel extension

Both, in moderation, are normal. Hand cycling and or riding the carrier seem to produce the worst, it seems.
