Ok, I have seen the videos of swapping barrels on the AI/AW and it appears to be rather straight forward with the right tools. I am getting an AI/AE next week and was told that you can also change the barrels on them but that it has a couple of other steps to it. Can someone tell me if I was informed correctly and that there are more steps to it or is it as easy as it appears on the AW. Also can I use the regular, read non AI certified tools to do it with? What I mean by that is being able to buy go/no go gauges for 30 bucks from midway instead of 300 plus dollar AI gauges and barrel vises? Thanks in advance, RG
