The KelTec SU-16C is a 5.56 NATO semi-automatic rifle (KelTec part no. SU16CBLK) built around an under-folding stock that shrinks the rifle from 35.5 inches down to 25.5 inches for easy transport and storage. As one of the more compact semi-auto rifles in our lineup, the SU-16C is gas-piston operated, keeps fouling out of the action, and accepts standard AR-15 magazines, so ammo and magazine logistics stay simple. It’s built for the shooter who wants a genuine go-anywhere 5.56 rifle for truck storage, camping, or a lightweight range gun. Adjustable iron sights and an integrated Picatinny rail on top of the receiver mean it’s ready to shoot out of the box or wear an optic.
