SO....
I bought an AR complete upper half. 20" bbl gov't. profile. 1:8 twist. (I believe it's a Green Mtn. barrel.) It came with a tag on it that said to clean the bore every round for the first 200 rounds. I've never heard of such a thing. What is this? Is it truly necessary? What are the negative ramifications of not doing it?
