The KelTec RDB 5.56 NATO Green is a 17-inch bullpup rifle that holds 20 rounds (KelTec part no. RDBGRN). KelTec designed the RDB with downward ejection, so spent casings leave the gun below the line of sight, and with fully ambidextrous controls. Two integral Picatinny rails give you space for optics and accessories. The color is green, which separates it from the Black and Tan RDBs.
