I'm something of a newbie but I've done a substantial amount of research before buying my first AR. I'm deciding between several RRA models but I have questions about the handle/mount options. I have no interest in the carry handle. If the detachable came with the assembled rifle I decide upon then I will probably have it off most of the time.
Options offered by Eagle for most rifles include the flat top, the tactical mount, detachable handle and Dominator EOTech. What is the difference between the tactical mount and the flat top?
I plan on buying optics in the near future but don't know what I want yet. I doubt I will go with EOTech so the Dominator isn't of interest. Will there be any necessary additions to the flat top or the tactical mount to accomodate most standard optics? Is there any advantage to one over the other?
Thanks in advance for any help.
