Abstract: A light assembly having a pre-defined shape is provided to be removably attached to a guide provided on a weapon. The light assembly comprises a housing provided with a reflector having a lamp at one end thereof and batteries for powering the lamp through a switch. The housing has a pair of lateral members which are movable between a retracted position and an extended position so that, when the members are in the retracted position, the light assembly has the above-mentioned pre-defined shape and when the members are in the extended position, they are adapted to engage the guide. Means for preventing the longitudinal movement of the light assembly on the guide are also provided with the light assembly. The light assembly can thus be easily mounted and used as an aiming device with a weapon or be readily used as a separate and independent entity.

Abstract: A light assembly having a pre-defined shape is provided to be removably attached to a mating guide provided on any convenient device but advantageously provided on a weapon. The light assembly comprises a housing provided with suitable optics having a light source at one end thereof and batteries for powering the light source through a switch. The housing has a pair of lateral members which are movable between a retracted position and an extended position so that, when the members are in the retracted position, the light assembly has the above-mentioned pre-defined shape and when the members are in the extended position, they are adapted to engage the mating guide. Means for preventing the longitudinal movement of the light assembly on the mating guide are also provided with the light assembly. In a particularly advantageous application, the light assembly can thus be easily mounted and used as a target illumination and/or aiming device with a weapon or be readily used as a separate and independent entity.

Abstract: An M16 or commercial equivalent style rifle buttstock is provided with a stowage compartment within the buttstock body for an M4/M16 style firearm or commercial equivalent that utilizes an adjustable receiver extension which is cylindrical with a radially disposed elongated rib. The buttstock can be inserted without any permanent modifications to the host firearm, and is completely reversible. Internal storage for accessories is provided, and the buttstock is able to accept standard M16 style or commercial buttplates, with or without hinged access doors to the stowage compartment. The buttstock provides an improvement to the ajustable buttstock used on M4/M16 style firearms in cold weather which can become frozen in place in the collapsed position and not provide a proper mounting of the carbine relative to the user. Additionally the buttstock provides all of the standard ergonometric relationships of an M16 style firearm or commercial variant for the user.

Abstract: A firearm interface for a buttstock and pistol grip that provides a means to attach a pistol grip or a buttstock assembly to a firearm, and shotguns in particular. It can be used for either modality individually or both in combination. It allows the utilization of an M16/M4 style pistol grip and the adjustable, as well as the fixed buttstocks of M4/M16 style rifles and carbines. The buttstock and pistol grip interface confers the ability to configure the firearm to different requirements and to the ergonometric needs of diverse individuals. By facilitating the use of M4/M16 style receiver extensions and M16/M4 style pistol grips the buttstock and pistol grip interface brings a vast array of options to the firearms to which it is affixed. For those individuals with military experience the use of M16/M4 style components imparts a degree of familiarity and utility.

Abstract: The front and rear sights for shotguns which are the object of the present invention provide the use of M16/M4 style sights within sight bases which can be affixed to the receiver and barrel of a shotgun. An enhanced level of precision as well as familiarity is imparted to shotguns which employ sights of the configuration described within the present invention. The addition of a M-1913 style rail base to the rear sight assembly brings the added benefit of the ability to add an additional sighting collimator to the rear sight assembly in terms of a reflex, or refractory optical sight which conveys the benefit of a co-witnessed sight alignment. The use of M16/M4 style sights which have proved the test of time in military deployments from the 1960's until the present time bring an operationally sound modality to shotguns that are tactically employed.

Abstract: A device for storing, transporting and mixing reactive ingredients, such as mercury and silver for dental amalgam, includes a thin, rupturable membrane dividing the two chambers of a capsular container into two non-communicating closed compartments, one for each of the reactive ingredients, the chamber of larger volume (major chamber) also including a pestle. Unlike conventional devices of this type, the membrane is ruptured substantially completely intact, i.e. without presenting any loosened or torn fragments of the membrane which could contaminate the mixed ingredients simply by inserting the capsule in an amalgamator or similar vibrating or shaking device. Since no manipulation of the capsule, such as telescoping, bending, twisting etc is required, mixing of the components can be performed with a minimum amount of effort.
