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 smoking pipe has upper and lower body portions removably magnetically connected to each other. The upper and lower body portions define an enclosed smoke chamber with the upper portion defining a receptacle. A plurality of openings communicate between the receptacle and the smoke chamber and the combined body portions define a passage between the smoke chamber and an outlet. The upper body portion has a planar lower surface and the lower body portion has a planar upper surface, and the upper body portion and lower body portion abut each other in a common interface plane. The upper body portion and lower body portion are detachable by sliding on the interface plane. The passage encompasses the smoke chamber and includes an arcuate portion encircling the smoke chamber including an opposite side of the smoke chamber, and the passage includes an enlarged portion configured to receive a filter.

Abstract: A support for a vehicle accessory flagpole comprises a ball hitch element having a receiver interface. The ball has a plurality of flat facets; a pole support having a flat bottom surface; and a clamp operably connected to the pole support and the ball to bias the flat bottom surface against one of the facets.

Abstract: A lower receiver for a rifle that comprises a rear surface defining a concave handgrip receptacle having a vertical tangent point at a first level. A trigger guard in part defines a trigger opening; the trigger opening having an upper limit surface at a second level below the first level; and a trigger lever extending downwardly from the upper limit surface.

Abstract: Latches for rifles have a body having a connection facility adapted to connect to the lower receiver, the body being movable between a first position and a second position, the body having an actuator surface adapted to contact the upper receiver and responsive to position the body in the first position in response to the upper receiver in the assembled condition, and to position the body in the second position in response to the upper receiver in the separated condition, the body having a block surface adapted to prevent movement of the magazine catch from the retention position to the released position when the body is in the first position and to enable movement of the magazine catch from the retention position to the released position when the body is in the second position, and a movable adjustor element connected to the body and movable within an adjustment range.
