This is one of the projects that we at ATS have been working on. It’s our co-witness, sub and carbine sight. We are zeroing in on the front to rear sight height ratio, so as to cover elevation adjustments from .223 to larger calibers, when using our shim system. This is tricky, because there is little uniformity between different picatinny rails, in terms of their individual geometry and how they are attached to the firearm. In addition, different calibers -- 223 and 30-06, for example -- may have very different elevation requirements.
However, it’s all starting to come together. In the end, we’ll have a top mounted ATS for rifles and carbines that will go on AR’s as a co-witness, AK’s, and sub-machine guns. What do you all think?
