Kel-Tec’s SU16 rifle series is chambered in .223 Remington and uses AR-15 magazines. It folds for storage and transport. A unique feature of the SU16 is the two 10-round magazines that store in the butt stock of the rifle. This means you have an onboard source of emergency ammunition. That's a great feature to have in a patrol rifle. The 1917-style mount on the SU16's receiver allows the user to mount a red dot sight or scope. It possesses a level of accuracy that should be more than adequate for a patrol rifle.
