Used, but in great shape.
Keltec describes rifle as "The "Charlie" model retains most features of the original SU-16, such as integrated bipod, Picatinny rail, and AR-15/M-16 magazine compatibility. The front sight is integrated into the gas block and uses an AR-15/M-16 style front sight post for elevation adjustments. The SU-16C has a true folding stock and can be fired with the stock folded. A reciprocating dust cover and a case deflecting operating handle are also integrated into the rifle. The medium weight barrel is 16" long and is threaded 1/2x28 TPI at the muzzle. Chrome lined bore and chamber are now standard. The "Charlie" is only available in Parkerized finish with black polymer components."
The "C" model is hard to find. Great shooting rifle, zero problems, a really neat gun!
