I'm in the process of picking out my first ar. I have a question on the barrels. What is the difference between the heavy M-4 barrel and the plain heavy barrel? What are the advantages or disadvantages of both? They are both 16" and both have a 1-in-9 twist. Thanks for any info.
Check out "Pros and Cons" in the Rifles, Uppers, Lowers, Barrels and More" forum.
Picking out first AR! Perhaps this will help.
