Indoor shooting range comprising an interior space for firing ammunition, said indoor shooting range comprising: —an air ventilation system arranged for providing said interior space with fresh air; —a detector unit arranged for detecting a concentration of metallic elements, in said interior space, originating from ammunition fired in said interior space of said indoor shooting range; —a control unit, communicatively coupled to said air ventilation system and said detector unit, for controlling said air ventilation system taking into account a detected concentration, by said detector unit, of metallic elements originating from said ammunition fired in said interior space for maintaining said concentration of said metallic particles in said interior space below a predetermined value.

A method for the design and development of new ballistic resistant articles is provided. Improved ballistic articles are formed of polyethylene-based composite laminated structures having unique material properties including material density, Poisson's ratio, and modulus of elasticity (Young's modulus). Cycle time for completing design and development is less than 30 calendar days.

A projectile trapping device for protecting objects from impact damage includes a shell, which defines an interior space. The shell has a front face, which is open. The shell can be positioned on a substantially horizontal surface between an object, such as a vehicle, a person, or glass, and a source of projectiles, such as a lawnmower, an edger, or a trimmer. The shell prevents projectiles propelled from the source from striking the object.

A weapon testing chamber is provided. The chamber enables the testing of conducted energy weapon (CEW) and contain any accidental discharges which may occur. In addition the chamber may also be utilized for safe unloading of a handgun by providing a testing chamber which can absorb any accidental discharges of the firearm and can accommodate differing models and types of weapons in a single testing chamber.

A firearm holster includes a plate that is folded to form a cavity. The cavity is defined by a first sidewall, a trigger sidewall adjacent to the first sidewall, a second sidewall adjacent to the trigger sidewall, a barrel sidewall adjacent to both the first and second sidewalls, and a muzzle end wall. The muzzle end wall is adjacent to the first sidewall, the trigger sidewall, the second sidewall and the barrel sidewall. The firearm holster also includes a support wrap that at least partially surrounds the cavity and is fused to one or more of the first sidewall, the barrel sidewall, and the second sidewall.

This disclosure is directed to an improved ballistic concrete barrier for stopping projectiles with a kinetic energy of between about 1.0 kJ (750 foot-pounds) and 20.3 kJ (15,000 foot-pounds) in between about 3 inches and 10 inches. In one embodiment, the ballistic concrete barrier comprises (a) about 1 part by mass Portland cement; (b) about 0.5 to 1.5 part by mass fine aggregate; (c) about 0.005 to 0.15 part by mass fiber; (d) about 0.005 to 0.05 part by mass calcium phosphate; (e) about 0.005 to 0.05 part by mass aluminum hydroxide; and (f) about 0.0005 to 0.05 part by mass air entrainment additive, such that the ballistic concrete barrier is capable of stopping a fifty caliber bullet in less than 10 inches from a point of entry into the barrier.

A system using Faraday's law to rapidly direct convert the kinetic energy of a magnetized and/or conducting projectile into usable electrical energy. The system includes a barrel comprising a bore; a circuit including a plurality of electrically conductive components distributed along a length of the bore; and a projectile comprising at least one of a conductive material or a magnetic material magnetically coupled to the electrically conductive components when the projectile is moving along the length of the bore. The circuit stores energy generated from an electric current induced in the electrically conductive components when the projectile moving along the length of the bore causes a magnetic interaction between the electrically conductive components and the magnetic material or the conductive material. The magnetic interaction also causes braking of the projectile.
