  • Patent number: 4932328
    Abstract: Stun grenade includes a steel housing having a steel tubular body with steel end members brazed to the ends of the tubular body, and a brass collar member threadably received in a threaded central opening in one of the end members for supporting an explosive charge in the housing. At the inner end of the collar member is a cylindrical portion to which a tubular container filled with the explosive charge is attached. The outer diameter of the tubular container is less than the minimum diameter of the threaded opening in the one end member to permit the tubular container to be inserted through the threaded opening while attached to the collar member. At the outer end of the collar member is a threaded recess for threaded receipt of a fuse member externally of the housing. A flash hole in the collar member directs a flash which is produced when the fuse member is activated into the tubular container to ignite the explosive charge.
