Technically it's a M16 without a three round burst, AR stands for armalite witch is a gun making company. Colt is one of the companies that make law enforcement M4 and M16 that also make competition models. They actually make some really nice guns. Your lucky I've seen rifles like that go from $600+, they shoot good as long as you know how to work and clean it you should be great.
