Looking to build a new 16" 556. With so many company's selling barrels, it's hard to decide which one is decent. This is where I need help, looking for a accurate barrel that's not going to break the bank. Have been looking at the bison armory ss barrel in a wylde chamber. Has any one had any experience with this barrels. I know there 6.8 barrels are very accurate. Our any other barrel company's to recommend?
