| Got my bcm 16 bfh upper in the mail. I understand you need to wipe down the factory oil and apply clp of your choice on the internal parts. Does that mean external parts as well and on the barrel itself? Sorry this is my first AR. Also does anyone clean it as well after wiping the factory oil? Just in case there's some unwanted debris |
