Let's see--you are considering getting rid of the most ergonomic, popular, adaptable, and effective defensive rifle produced to date; one where there are plentiful stocks of parts, magazines, and ammunition for long term service in CONUS.....hmmmm, maybe not a wise idea. Keep the AR15's. While AK's are fine carbines, every qualified American should own an AR15. Perhaps more Americans have been trained to safely operate the AR15 than any other firearm. There are approximately 25 million American veterans who have been taught how to properly use an AR15 type rifle through their military training, not to mention in excess of 1 million American LE officers who have qualified on the AR15 over the last several decades. In addition, there are numerous civilian target shooters and hunters who routinely use AR15's. In many ways, the AR15 is the ubiquitous "Brown Bess" musket or Winchester repeating rifle of the modern era—a true firearm for the people of America. The AR15 is a highly versatile design that can be adapted for military, law enforcement, civilian self-defense, hunting, target shooting, and other sporting purposes--something an AK cannot match. If you want AK47/AKM performance in an AR, run .300 BLK. Yeah....keep the AR15.
