I stopped at the browe optics booth on the last day of shot show. Brian browe came out of the trijicon design house. Brian made improvements to the ACOG system. He got rid of the tritium illumination system that wears out to you too radioactive decay and replace it with a battery powered illumination system. He uses a c r 123 battery that is commonly available. The scope body material is made of titanium. He has a dedicated 300 blackout optic. I am currently using the same optic on my 300 blackout.
