This has really gotten my attention. http://dynamicarmament.com/items/ar...kit-adams-arms-5-45-conversion-kit-detail.htm I was considering one of the current crop pf Bulgarian AK-74s to plink with the cheap corrosive milsurp ammo but they've had their barrels replaced with non-chrome lined U.S. barrels (who made that brilliant decision?), but this kit is the equivalent of chrome lined and is even less expensive, assuming you have a donor AR upper. Anyone have any experience with an Adams Arms conversion kit? Just what kind of tools do you need to replace the barrel, gas block, etc? Is it something an all thumbs monkey can do or would I need to have a smith do it?
