Speaking of the AR platform, it's the rifle equivalent of the small block Chevy engine. Endlessly customizable. They range from the cheap plinkers that rattle to the high end precision guns that are as tight as a bank vault. The caliber options are only limited to what you can fit in the magazine and the quality of parts available can put you up into custom bolt gun price ranges.

There are also the older, classic designs like the Garand and M14. Then there are the newer players like the SCAR and others.

If some people don't like "black rifles" what do they think of the chassis based bolt guns?
