The KSG is KelTec’s bullpup pump with two tubular magazines under the barrel and a selector to choose which tube feeds. This KSGGRN OD green set uses an 18.5″ cylinder-bore barrel and a 3″ chamber. Capacity is typically 6+6+1 with 3″ shells (14+1) or 7+7+1 with 2¾” shells. Top and bottom Picatinny rails support optics and accessories. Compact overall length for vehicle and home use — no factory optic.
