Best AR-15 Barrel

They say buy the best trigger, barrel and bolt you can afford for your AR-15 and the rest is all something of a wash anyway. And this is pretty much true. A fancy name brand lower sold by some guy with a tactical beard is useless if you put a garbage barrel on your gun. You are going to want the best AR-15 barrel you can afford. 3-4 MOA is the standard accuracy for a barrel, and quite frankly that is boring. I’ve had AK’s that were more accurate. Let’s look at some of the best AR-15 barrels you can buy right now.
