Abstract: A substantially flat shutter plate is mounted for sliding movement on a shutter mounting means secured to the front of a laser aiming device housing. The shutter plate is substantially L-shaped to provide a fingerpull by contact with the shorter leg of the "L" and is slidable within a track formed in the rear surface of the mounting means, and includes in tandem, a first opening, a second opening and a solid portion, which can be used to aim a laser beam emitted from the laser aiming device housing, clean the laser tube, and shut the housing, respectively.

Abstract: A mount for attaching a device to a firearm includes a longitudinal base adapted to carry the device to be mounted. The base has a track extending along a portion of the length thereof and a block is slidably mounted in the track. The block is biased toward the front end of the base by a spring. The block is adapted to be attached to a first fixed member at one end of a firearm barrel. The rear end of the base is adapted to be attached to a second fixed member at the other end of the firearm barrel. When properly mounted between the ends of the firearm barrel, the mount is held in place by the action of the spring, which forces the block attachment against the first fixed member and the rear attachment against the second fixed member. The rear attachment also includes spring means to prevent the mount from wobbling from side-to-side when attached to the first and second fixed members and a thumbscrew for locking the spring means to the second fixed member.

Abstract: A quick release mount for securing an aiming device such as a laser on the barrel of a rifle includes a forward and rear mount shiftably mounted on a base plate to which the aiming device is permanently secured. The forward mount includes a spring-loaded slide member slideably mounted on the base plate and a split ring secured to the slide member which is sleeved over the barrel and biased into sliding engagement with a stop member on the barrel, such as a flame arrester. The rear mount includes a body member provided with slots and a locking mechanism for releasably receiving a shoe which is permanently secured to the barrel. The front mount includes an elevational adjustment while the rear mount includes a windage adjustment mechanism.
