The KelTec SU-16A (brand part no. SU16ATAN) is a lightweight, folding-stock rifle chambered in 5.56 NATO, built around an 18.5-inch barrel with tan furniture for a distinctive look beyond standard black. 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 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 barrel length.
