摘要:
A lighting device may include a light source and a reflective optical element. The reflective optical element may have a reflective internal surface that defines a cavity. The internal surface may include longitudinal undulations. The internal surface may be faceted or non-faceted. The light source may be at least partially disposed in the cavity. The shape profile of the internal reflective surface in any plane containing the surface's symmetry axis may be non-paraboloidal and may exhibit undulations running along its length. The reflective optical element may be a monolithic structure and may be a beam-shaping reflector that generates a light beam that, in comparison with a paraboloidal reflector having the same hole size, aperture size, and light source, is relatively fainter at small off-axis angles, brighter at mid-range off-axis angles, and fainter at large off-axis angles than a light beam generated by the paraboloidal reflector. Related methods are provided.

A forend (100) for a firearm (10) includes an adapter module (124) configured to mount below a barrel (20) and in front of a receiver (18) of a specific model of a firearm, such as a shotgun, and a universal firearm accessory module (104) coupled to one or more surfaces of the adapter module. The adapter module can include an upper surface (106) that substantially conforms to a lower surface of the barrel, a longitudinal bore (108) configured to receive a tubular magazine (22) of the firearm concentrically therein, and lower and external side surfaces defining a plug (110). The accessory module can include a firearm accessory and an upper and internal side surfaces defining a socket (116) configured to receive the plug of the adapter module in a complementary plug-in engagement. The accessory can be a source of a light (118,120) useful for illuminating a target or aiming the firearm.
摘要:
A method of aligning a firearm sound suppressor (100) includes inserting a front portion of a body of an adapter (168) into a socket (164) of the firearm sound suppressor (100). The method also includes sliding a tab (172) of the adapter (168) into a slot (166) disposed in an interior surface of the socket (164) to rotationally align the firearm sound suppressor (100) relative to a firearm. The method also includes contacting a plug (170) of the adapter (168) against the interior surface in a complimentary engagement. The plug (170) is provided by a frusto-conical external surface of a rear portion of the body. The tab (172) extends from the plug (170).
摘要:
In accordance with the present disclosure, novel quick draw hand gun holsters are described, together with methods for using them, that are capable, at a user's option, of activating a light accessory, such a light and/or laser sighting device, when the gun is drawn from the holster, and of deactivating it when the gun is inserted in the holster. Additional embodiments are also described.
