Abstract: A free float handguard for a firearm having a barrel includes a handguard body and a locking arrangement. The locking arrangement includes a barrel locker and a handguard locker. The barrel locker includes a first tubular locker adapted for coaxially coupling at a fixed end of the barrel, and a second tubular locker coaxially and rotatably coupled at the first tubular locker. The handguard locker has a rear portion coaxially coupled at the first tubular locker to prevent the handguard locker from being rotated therearound, and a front portion engaged with the second tubular locker to prevent the second tubular locker from being rotated around the first tubular locker, wherein a first end portion of the handguard body is coupled at the handguard locker for locking up the handguard body around the barrel in a free float manner.

Abstract: A flip-up aiming sight for a firearm includes a mounting base having a top platform, an illuminator embedded under the platform of the mounting base, and a flip up lens module which includes a lens frame pivotally coupled at a front side of the mounting base and a reflecting lens encirclingly mounted at the lens frame. The flip up lens module is arranged to pivotally fold between a folded position and an unfolded position. At the folded position, the lens frame is rearwardly and downwardly folded flat on the platform of the mounting base, and at the unfolded position, the lens frame is frontwardly and upwardly moved from the platform, such that the illuminator generates an aiming point on the reflecting lens.

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.

Abstract: A keymod mount, which is arranged for detachably coupling at a firearm having one or more keymod slots, includes a securing member and a locking member movably extended from the securing member. The securing member includes a mounting body having a top utility surface, and a coupling head downwardly extended from a bottom surface of the mounting body for slidably engaging with a narrow slot portion of the keymod slot to retain said mounting body on a top surface of the keymod slot. The locking member includes a locking body and a locking head downwardly extended from a bottom surface of the locking body for inserting into an enlarged slot portion of the keymod slot after the coupling head is engaged with the narrow slot portion thereof, so as to securely lock up the securing member on the firearm.
