KP-9 has a hinge block with a quick detach swivel mount and is SBR ready. This makes it a must have for the individual that would like to be able to shoot while waiting for their SBR paperwork to be approved by the BATFE or for someone that just really doesn't desire the extra length the stock and barrel of the KR-9 add to the platform. KP-9 comes with a hinged top cover with attached Picatinny rail and a 0.5x28 threaded flash suppressor. - 30 Round Magazine - OAL 18.25 - Barrel Length 9.25 - Weight 5.62 lb - QD Mount
