Hello, I am interested to know what you mean by "lower 1/3 co -witness".

Does this mount provide a true 1/3 co-witness with the Sparc AR or is it a lower than normal 1/3 co witness?

I hate to bring a post back from the dead, but I'm also interested in an answer to the question. I grabbed a American Defense mount(for T1) that was advertized as lower 1/3 cowitness....but I couldn't see the irons due to the Sparcs design. I'm hoping this mount is designed specifically for the Sparc AR and will give a true Co-witness
