Description Extremely rare and desirable MB Associates Mark II Model C 12mm GyroJet Rocket Pistol. Made famous in the James Bond thriller You Only Live Twice, the GyroJet concept used a proprietary rocket fuel housed in the body of the projectile that propels the projectile through 4 angled ports at the rear with the angle creating spin. The design was touted as having the ability to shoot underwater or in Zero gravity. This example with serial number 584 and 5″ barrel is a post 1968 NFA Act example in 12MM. Included is the original MBAssociates factory box, purchase receipt, and a certificate issued to Lt. Commander John R. Damon after firing the gun and naming him a “Rocketeer”. Ships to FFLC&R Only. Condition: Like New condition showing no signs of any use other than the one round identified in the certificate. The bore on these are smooth and this example shines like a mirror. The action functions properly and as expected. Barrel Length: 5″ Serial: 584 Manufacturer: MBAsscociates Year: 1973 Caliber: 12MM Model: MarkII
