An accessory mount for a firearm, and a method for installing the accessory mount to the firearm. In combination with the firearm including a longitudinal barrel, a rear support and a front support, the accessory mount includes a first semicylindrical mount housing having two longitudinal edges, an inner surface and a rear end, the first housing positioned along the barrel with its rear end supported by the firearms rear support, and including longitudinally spaced-apart lugs on the inner surface adjacent to each of the first housings edges; a second semicylindrical mount housing having two longitudinal edges and a front end, and including longitudinally spaced-apart appendages adjacent to each of the edges of the second housing, the second housing placed to the first housing with the appendages cooperating with the lugs for transversely securing the first housing to the second housing and with the first and second housings longitudinally movable relative to each other; and at least one longitudinally adjustable member carried by one of the housings longitudinally urging the first housings rear end against the firearms rear support and longitudinally urging the second housings front end against the firearms front support.

A flashlight has a lens having an optical axis, with a first light source positioned on the optical axis. A second light source is spaced apart from the first light source away from the optical axis, and the lens has an aperture registered with the second light source. The lens may have a central portion configured to transmit axially-emitted light from the first light source, and the lens having a peripheral portion having an internally reflective surface configured to reflect laterally-emitted light from the light source in a direction more closely aligned with the optical axis. The first light source may be positioned within a recess in the lens, and the aperture may be formed in the peripheral portion of the lens. The light sources may be LEDs, and may be of different colors.

A flashlight has a lamp, a power source, two switches, and a controller connected to the switches. The first switch controls delivery of power to the lamp, and the second switch selects a dimmed brightness level. The first switch may invoke the dimmed level, or a maximum brightness level. The second switch may be a ring rotatable about the axis the flashlight, and either rotatable through a wide range of positions, with sensor circuitry to detect the absolute position, or having a limited range of rotation, with dimmed level selection provided by a duration of momentary rotation in either direction. The second switch may be positioned outside a leak resistant housing, and may include a magnet detectable by magnetic field sensors within the chamber.
