Hello all, I am getting ready to purchase an optic for my 14.5 carbine upper i built. And had my mind set on $490 or less. So i have the eotech 512 for $400 shipped, ot the aimpoint C3 with a adm 68h mount for $490 shipped, or i even thought about going with the burris fastfire II with the new Burris AR-F3 Flattop Fast Fire Mount for about $300 shipped. The burris is the most tempting because of the price, but i know you get what you pay for. I have had a eotech 512 before, and liked it, but was thinking about trying a aimpoint , but would hate to spend all that money and not like it.
