Abstract: A magazine tube and barrel clamp with integral target illuminator, wherein a laser module can be incorporated is provided for a firearm having a magazine tube and a barrel. The frame defines a clamping sleeve for substantially encircling the magazine tube and a barrel receiving channel for receiving a diameter of the barrel, wherein the magazine tube and the barrel are thus fixed in a predetermined spacing. The frame further defines an illuminator recess for receiving a substantial portion of a reflector in the target illuminator, thereby shielding the target illuminator from contact with external surfaces. A driver circuit is retained within the frame to selectively operate the target illuminator and a laser sight, wherein the target illuminator can be a solid-state light emitting device.

Abstract: A flexible air hose comprises a plurality of hose sections, each having at one end a female portion and at an opposite end a male portion coupled inside the female portion of an adjacent hose section. A loop coupling fastener is attached to an inside surface of the female portion, and a corresponding area of an outside surface of the male portion. A single slit extends from an end edge of the female portion of the hose section longitudinally along the hose section such that the female portion can be opened along the slit to facilitate positioning the male portion inside the female portion. A flap can be provided to cover the slit, and extend past the slit end to reduce air leakage. A wear strip can be wrapped around the hose.
