Just picked up my new WW (R16M4A4T) carbine on Monday! This is my first AR purchase. This model seems to have most, if not all, of the features of higher priced ARs: Well made M4 feed ramps, chrome lined 4150 steel barrel, 5.56 chamber, properly staked bolt key, shrouded firing pin, etc. Paid $905 out the door. I've heard many schools of thought regarding a proper break-in for chrome lined vs standard barrels. Some even recommended cleaning the bore between each shot. I'd like to hear from you AR freaks: How would you recommend breaking in the new rifle? Thanks in advance!
