The KelTec SU-16B 5.56x45mm NATO Folding Rifle (brand part no. SU-16B-CK-TAN) is built around KelTec’s distinctive forward-folding stock, collapsing the rifle down to a compact package for storage or transport without tools. Finished in Tan with a 16-inch barrel, this semi-auto rifle pairs an adjustable peep sight system with a lightweight, sporting-configuration build that stands apart from a standard AR-pattern rifle. It’s well suited to truck guns, backpack storage, and shooters who want a full-length rifle that folds down small when it’s not in use. The SU-16B ships with one 10-round magazine.
