Manufactured between 1962 and 1970, the Gyrojet pistol was intended to replace the standard powder filled cartridges with a super high velocity "rocket" type cartridge. In place of a traditional cartridge, it instead fires a self contained spin stabilized solid fuel rocket, removing the need for a strong breech or precise gas sealing. A sliding action cover takes the place of a traditional slide and is ported to direct the escaping gas to the sides, away from the shooter. The grips are smooth hardwood with a proper cutout on the left side for the magazine follower. Included with the pistol is a MBA hardwood case with a Robert Goddard medallion and eleven rounds of ammunition.

Excellent with 95% original finish, showing mostly light handling marks and some light surface scratches. The grips are also excellent with light handling marks. Mechanically excellent. The case is very good with some storage marks and staining. The aluminum ammunition has oxidized to a white patina.
