The KelTec SU-16C (brand part no. SU16CGRN) is a lightweight, folding-stock rifle chambered in 5.56 NATO, finished in green for shooters who want a compact, easy-to-store carbine that still runs a full 16-inch barrel. Its folding stock design lets the rifle collapse down to a fraction of its length for storage in a backpack, truck, or safe, then deploy quickly when needed. A peep sight and push bolt safety keep the manual of arms simple, while the standard AR-magazine compatibility keeps ammunition and spare mags easy to source. This is a genuinely different take on the modern sporting rifle, built around portability without giving up a full-length barrel.
