Abstract: A slide assembly for a firearm comprising a slide and an extractor assembly is provided. The slide includes a mounting recess about a top side of the slide, and a housing recess about a proximal end of the slide. The extractor assembly is mounted within the housing recess and includes a distal end for engaging a cartridge and a proximal end opposite the distal end. The proximal end terminates at a position adjacent about a mid-portion of the mounting recess. One or more retaining holes are provided within a proximal region of the mounting recess spaced from the proximal end of the extractor assembly. Firearm sights are attachable to the mounting recess via fasteners engaging the retaining holes. The retaining holes are arranged such that they do not interfere with the extractor assembly or other components within the housing recess of the slide.

Abstract: Takedown pins for rifles have a pin movable in a direction along its length between an operating condition and a released condition. The pin has a first end portion that prevents relative movement of the upper receiver with respect to the lower receiver when the pin is in the operating condition. The first end portion has a lower end portion surface adapted to resist upward movement of the upper receiver's lug. The pin has an intermediate portion adjacent to the lower end portion surface defining a lower channel having a lower channel surface above the level of the lower end portion surface. When the pin is in the released condition, the lower channel is registered with the lug, and the lug is enabled to move upward with respect to the lower receiver by a limited distance to a disengaged position.

Abstract: A single-wire serial data communications bus is established between an electronic accessory, such as an optical laser sight, and a host controller, using an externally accessible connector on the electronic accessory generally having another primary purpose, such as connection of a remote switch. The need for more complex connection schemes for calibration and control of the electronic accessory is thus eliminated. Furthermore, the single-wire bus enables a range of other host devices, such as a smart switch or an ambient light sensor module, which may provide more complex control options by sending serial control commands to the unit. Additionally, connected hosts may be parasitically powered through the communications bus to eliminate the need for separate batteries.

Abstract: A bullet resistant security fence is formed by a plurality of horizontally oriented formed metal panels extending between I-beam support posts. Each panel can be an extrusion having a hollow void for insertion of optional insert modules to enhance the bullet resistant capability. The insert module can be formed as a sandwich with alternating layers of metal sheeting and furniture grade plywood, screwed together to create an integral module. Each panel extrusion includes a tongue and groove interlocking configuration to resist penetration of the fence between metal extrusions. Construction is accomplished by stacking the metal extrusions between spans of adjacent support posts and securing the metal extrusions with a cap, which can include a louvered topper for the fence. Crash protection can be obtained by running cables through the voids in the lowermost extrusions and holes drilled through the support posts, and anchoring the cables at opposing ends thereof.
