I recently worked a trade deal for a Daniel Defense M4 v3 from the friend of another forum member here (Thanks Demasoni and Justin). I have an Aimpoint Comp M3 on my other AR carbine and am looking to get a red dot for the DD carbine. I like the Aimpoint, but have also heard good things about the Eotech 512 and it is less money than the Aimpoint. I am interested in feed back from anyone who has experience with both and pros and cons as to which one you may prefer and why. Thanks for any input.
