I have started gathering parts to build an m4gery, and I think that I want a 16" bushmaster m4 profile barrel. I like the Idea of chrome lining the barrel and chamber for durability and ease of cleaning, but I have heard that as a rule, chrome lined barrels are less accurate than non chromed barrels, but I have also heard that bushmaster has some special process of lining their barrels to make them just as accurate as a non lined barrell. So, long story short, I was wondering if anyone knows where I can order a bushy barrel for less than straight from bushmaster, I am also interested in other brands of lined barrels if they are accurate. I should probably also say that when I say accurate, I want this gun to be able to hold MOA out to 200 yards or so, as I will use this rifle to hunt coyotes from time to time. Thanks for any info.
