the galil is sometimes refereed to as the anti AK. it takes the AK platform, maes it a little more ambidextrous, a little more comfortable and makes it NATO compatible. it keeps all the AK advantages over the M16 and removes a lot of the weaknesses. you will never find a galil in 5.45 but that doesn't mean you cant finagle a somewhat decent copycat.
galil style furniture for AKs are fairly common and if you know anyone that's good with a welder, some companies make kits to give your AK a vertical charging handle. slap those on an AK74 and you'd have a 5.45 galil copycat.
