Argh. Here we go again.
You're right, we have been over this about a dozen times in the last 5 or 6 months.
What do you want to do? Clear rooms? Or shoot 100 yard groups?
Red dots and EoTechs and ACOGs are all good for close up, eyes open, close contact drills and fighting.
They are not so much for stringing together 100 yard groups to see what the rifle can do. Most of the reticles will cover your 10 ring at 100 yards to be honest.
A nice 3x9 power scope would be ideal for 100 yard work, and if you get some quick release ARMS, or similar, throw levers, you can pull it, snap on your Red Dot or Aimpoint, and go room to room. Or get a good set of folding BUIS ( Back Up Iron Sights ) and pull the scope, pop them in place and do your close range work.
I have an EoTech on my CQB model, and I love it, but it's for street to street style engagements. I know I can hit minute of bad guy all day at 200 yards and that is all I care about for that weapon.
If I were building a Tactical Support Weapon, I would want good glass on there though so I could make more pinpoint shots.....
So the question is really application....
Best of luck!
