Abstract: A dry fire trigger device for dry firing a lower receiver of a firearm having a magazine well, a trigger, and a hammer, the dry fire trigger device comprising is provided. The dry fire trigger device includes a lever housing shaped to engage the magazine well of the lower receiver and a lever movably secured to the lever housing. The lever includes a hammer contact portion shaped to contact the hammer of the lower receiver. The hammer contact portion is adjacent the hammer of the lower receiver when the device is secured in the magazine well of the firearm. In a first position the hammer contacts the hammer contact portion of the lever when the trigger is pulled and further wherein the movable lever substantially re-cocks the hammer after the hammer contacts the lever when the lever is moved to a second position.

Abstract: Reactive sintering process for producing a shaped body containing the nickel aluminide compound Ni.sub.3 Al, which comprises sintering a compacted shaped mass containing an intimate mixture of substances, e.g. including elemental nickel powder and elemental aluminum powder in a stoichiometric atomic ratio generally corresponding to the compound Ni.sub.3 Al, by heating the mass, e.g. in a vacuum, to an elevated sintering temperature, e.g. 500-750.degree. C., sufficiently to initiate an exothermic reaction, and at a heating rate sufficiently for consequent progressive generation of a transient liquid below the melting point of the aluminum powder and at the corresponding eutectic temperature, and upon initiation of the exothermic reaction continuing the sintering sufficiently to form a densified shaped body containing the nickel aluminide compound Ni.sub.
