A weapon accessory mounting bracket comprises a main body 1 with a jaw 2, and a clamp block 3 with a jaw 4 facing the jaw 2. The main body 1 and the clamp block 3 may be urged together by rotating a cam lever 7, allowing the bracket to be mounted on a weapon accessory rail such as a Picatinny rail. The jaws 2, 4 are biased towards each other by a resilient member such a coil spring 11. This allows the bracket to be mounted to the rail and prevents it from falling off while the user moves his hand to the cam lever 7 to lock the bracket in place. In an embodiment, the closing bias of spring 11 is countered by an opening bias supplied by two coil springs 8. Unless cammed together, the jaws 2, 4 thus float in a correct, partially open position and are able to receive an accessory rail at any time. The mounting arrangement allows accessories to be attached or detached at speed, under stress, in extreme conditions or with the user encumbered by protective clothing. |
