Was having issues with this unit shutting off under recoil. I sent it into Eotech and had it repaired and updated, so its pretty much brand new again. I remouted it and ran a hundred rounds through it to verify everthing was good. I would like $300 shipped via discreet paypal. Don't need to sell, only selling because I want to try a low power zoom scope. Original date of manufacture was December 2007.
