Abstract: A sight module for a firearm having a barrel axis includes a base for detachably attaching onto the firearm, a first optic upwardly extended from the base to define a first sight axis parallel to the barrel axis of the firearm, and a second optic sidewardly extended from the first optic to define a second sight axis parallel to the barrel axis of the firearm and orientated at an offset angle with respect to the first sight axis, wherein a distance between the first sight axis and the barrel axis equals to a distance between the second sight axis and the barrel axis. Therefore, a user is able to maintain the same cheek weld on the firearm stock to view one of the first and second optics in order to quickly switch between the first and second optics by simply rotating the firearm.

Abstract: A KeyMod quick mounting arrangement is arranged for detachably coupling an accessory at a firearm having a KeyMod mounting slot, wherein the arrangement includes a mounting body having a first side extended from the accessory to be detachably coupled with the firearm, and a coupling head movably extended from the mounting body between a releasing position and a securing position. The coupling head has a head portion outwardly protruded from an opposed second side of the mounting body, wherein the mounting body is stationary when the coupling head is moved between the releasing position and the securing position. In the releasing position, the head portion of the coupling head is disposed in an enlarged slot portion of the mounting slot. In the securing position, the head portion of the coupling head is slid to a narrower slot portion of the mounting slot for securing the accessory at the firearm.

Abstract: A firearm mount for a firearm includes a mounting body, a sight module, and a mounting interface. The mounting body has a first mounting face adapted for detachably coupling with the firearm and an opposed second mounting face. The sight module is supported by the mounting body between the first and second mounting faces thereof. The mounting interface is provided at the second mounting face of the mounting body to define a mounting direction aligning with a barrel axis of the firearm.

Abstract: A lens cover for a lens equipment includes a tubular cover body for detachably coupling at a lens housing of the lens equipment in front of a lens thereof, a cover module, and a locking mechanism. The cover module includes a cover panel and a joint unit coupled between a sidewall of the cover body and a peripheral edge of the cover panel to enable the cover panel to be moved between a covered position and an uncovered position, wherein in the covered position, the cover panel is supported at a front portion of the cover body for covering the lens, and in the uncovered position, the cover panel is rotated sidewardly about the joint unit for uncovering the lens. The locking mechanism is provided at the sidewall of the cover body for releasably locking the cover panel in the covered position.
