I just put an Eotech 512 on my Ar-15 last week. It is absolutely perfect with all accessories and orginal cases. Now, I am thinking I should have put a scope on it. I am looking for a 1-4 Vortex Viper PST. I am looking to trade pretty much straight up, or I'll put some cash on the deal if the scope is in really good shape and/or has a mount. Let me know if you are interested.
