A device for arranging an accessory on a firearm, in particular a handgun, is provided, wherein the device has a housing for receiving the accessory in the housing, wherein the housing can be fastened to the firearm, wherein the housing has a first portion with a front end wall and with a rear end wall at a distance from the front end wall, the housing has a second portion, which protrudes axially at the rear end wall of the first portion, the second portion has a fastening device for fastening the housing to the firearm, and the housing has a substantially L-shaped basic form. A firearm with a device for arranging an accessory on a firearm that is arranged on it or can be arranged on it is also provided.

An LED light source capable of projecting a set graphic logo and red dot sight thereof, comprising a point light source (1) and a peripheral light source (2) around the point light source (1), the peripheral light source (2) being discontinuous line light source. The LED light source capable of projecting the set graphic logo does not need a raster being matched with transmission to obtain an LED with luminous set graphic logo, so that the power consumption is reduced, system design is simplified, product functions are increased, and simplification of structure, convenience of operation and reduction of cost for red dot sight are facilitated.

An accessory mounting system for securing an accessory to a firearm includes a slot in a first end of a receiving portion of the firearm, a tab protruding from one end of the accessory, the tab structured to mechanically engage with the slot, and a fastener structured to clamp a portion of the accessory to the receiving portion of the firearm in a location apart from the slot.

A mountable light includes a light body and a mounting arrangement including first and second clamping members from a set of pairs of clamping members. The light body has first and second opposing receptacles in which the respective clamping members are respectively removably disposed to move toward and away from each other. One clamping member may be fastened in its receptacle so as to be a fixed clamping member while the other clamping member is movable. A clamping mechanism may move the clamping members closer together to engage a mounting rail or away from each other to release the rail. An interchangeable key member may be provided between the clamping members, and may be selected from a set of interchangeable key members.

A clip-on display for mounting to a riflescope may include a clamp member. The clamp may include first lateral member. The clamp may include a second lateral member spaced apart from the first lateral member. The clamp may include a collar that extends between and couples the first lateral member and the second lateral member. The clamp may include a first clamp arm and a second clamp arm. Each of the first clamp arm and the second clamp arm may include a fixed end that extends from the first lateral member and a free end that is coupleable with the second lateral member to tighten the respective clamp arm. The clip-on display may include a beam splitter coupled with the clamp.

An offset optic mount can be detachably mounted to an accessory rail of a firearm in a cantilevered fashion with its distal end extending laterally from the firearm. An offset optic mount includes: a base adapted to be mounted to the accessory rail; an optic adapter plate configured so that an optical sight can be attached thereto, the optic adapter plate is offset at an angle relative to the longitudinal axis of the base; and a stem adapted to connect the optic adapter plate to the base, the stem is a reversable piece used to set and change the offset angle of the optic adapter plate relative to the longitudinal axis of the base.

A mounting system includes a bracket, a first engagement member, and a second engagement member. The bracket includes a first leg, a second leg, and a bridge portion extending between the first leg and the second leg. The first leg defines a first aperture. The second leg defines a second aperture. The first engagement member is disposed within the first aperture and includes a first engagement surface. The second engagement member is disposed within the second aperture and includes a second engagement surface configured to receive the first engagement surface.

An accessories mount, for weapons equipped with a tactical rail, comprises a quick-release clamp for a light and a pressure switch for actuating the light. This enables one light to be used on multiple weapons and to be readily mounted or de-mounted for charging the battery(ies) or using unattached to a firearm. The light may also be recharged while still clamped to the mount.

A method of aligning a point of aim with a point of impact for a projectile device is disclosed. Using a superposition device coupled to the projectile device, at least three reference points are superposed within a first target area with at least three diverging beams of the superposition device. Positions for at least three of the reference points are noted. A projectile is shot from the projectile device at a second target area, while the positions of the at least three reference points are maintained, to create the point of impact. The point of aim for the projectile device is adjusted to correspond with the point of impact while the positions of the at least three reference points are maintained. A system for aligning a point of aim with a point of impact for a projectile device is also disclosed.

An optical aiming device that includes front and rear mounting rings having protrusions configured to engage grooves in a cylindrical body for alignment of the optical aiming device.
