hey guys I need some help with choosing an optic for my AR. I have been looking at a EOtech 512 and a Burris tac 30 with fastfire 2 or 3. I am shooting to 300+ yards and didn't know if anyone on here had any experience with the burris. Ive been looking at reviews online and they both have there ups and downs just like anything else out there on the market today. Im leaning more towards the burris due to it having 2 optics in one the scope + the red dot. Any help would be great.
