I picked up this rail system before I knew it did not co-witness with an EoTech. Guess I should've read posts on the thing more carefully before I purchased it -_-;
It is unopened and sealed in the original box I received it in.
It is one of their green uppers which goes for $295 on their website. I'll do $250 plus actual cost of shipping on it if anyone is interested. Drop me a PM, thanks ^_^
