Nice work. A small disc is good for plinking and hunting when you don't want a larger one restricting your field of view. For quicker target acquisition.I have never liked the little 3/8“ aperture on the Williams diopter. With everything coming to build extensions, I decided to start working on the aperture. Getting it closer to eye is a concern. Bigger is safer. Prototype #1. Have one another in the works. This one is made for the extensions and would have to be trimmed a bit if directly over the receiver.View attachment 385924View attachment 385926
