Abstract: An accessory mount for removably attaching an accessory to a firearm rail includes a base having a mounting rail, a lock block moveable in a recess of the base and a throw lever, which when activated, allows springs to move the lock block in the recess so the lock block disengages the firearm rail in an open mode. The thumb lever also can engage the lock block to a closed mode in which it clamps the mount to the firearm rail in a fixed position relative to the firearm. An accessory thus can be firmly, consistently and securely mounted relative to the firearm with the mount. The thumb lever can be joined with a threaded shaft that engages a threaded element, for example, a keps nut, associated with the lock block. A toggle lock can selectively engage notches in the threaded element to set the overall clamping force of the lock block and mount on the firearm rail.

Abstract: A pistol slide racking tool has a main body with a threaded passageway through its upper section. Tapered lateral arm members extend from the upper section. Tapered attachment pads are located adjacent to each arm member. A shaft threadably engages the passageway through the main body. The shaft is connected to a handle at one end and, at the opposite end of the shaft, is in contact with a mid-linkage member located in the passageway. In order to rack the slide, the attachment pads are positioned adjacent to the sides of the slide. The shaft is rotated to move the mid-linkage member and attachment pads forward such that they are tight against the slide. Movement of the handle in the direction away from the pistol then racks the slide.
