Lockbar Rear Sight Parts

I've been asked many times for just a component of the Lockbar Rear Sight, so this is the result. All of these parts are USGI unless other wise stated. I have a large variety of all types of early SA and Winchester Windage Knobs. Probably the best on the net. Most are NOS still in grease. The smaller parts are more limited so get them while you can. Thanks
