Keep an eye on the EE on AR15.COM there's always some good deals on Eotech's. I got lucky at Tanner last week and picked up a 512 NIB for $309.Deals are out there if your not in a rush !!From what I've been told the Bushnell is the Eotech without the cover and waterproofing-same company.That's what I've been told but I don't know it for fact.
