I was looking at a bunch of barrels from diff websites and what they had in stock. I'm kinda confused. Some listed a .223 rem and some .223 ackley and some .233 rem/ackley. I have a standard 111 .223 rem. Are The barrels the same? I'm looking at the mcgowen stock list and its perfect for what I want but it says ackley. Not rem.... sorry, newbee queston,.
