    Just ordered my first BCM URG. It'll be a 14.5 mid-length with FSB and DD 9" lite handguards. I'll be running her on my spikes assembled with DD lpk and vltor A5 Emod until my BCM blem lower arrives. I'll put an Aimpoint T1 on a larue 660 and we'll be ready to roll. As this will be my first red dot ( I've always had holographic ) does anyone suggest 4moa or 2moa dots? I would like to be able to reach out to 250m max.

    At 250 Meters (what? About 273 yards?) I would think a 4MOA, and even a 2MOA, reticle is going to be a hinderance. You are going to COVERING your target with a giant red fore-front dot without the ability to make minimal changes should you miss. ;)

    Across the street or room-to-room, a 4MOA is going to be a benefit, but once you stretch that target out to even 100 yards, you are giving yourself a handicap.

    4MOA at 100 yards is going to be, roughly, a 4 inch circle. A little over 8 inches at 200 yards and your target is getting smaller with each foot traveled.

    I am a big fan of the heads up display offered by many modern reticles and CQB scopes. Having said that they are not for "longer" ranges because they completely cover the target with a big red dot.

    You might want to consider a quick release scope in a 4x or 6x power for longer ranges and a heads up CQB sight for when you are truly shooting at "short/CQB" ranges.

    I'm just going for man hits not 1 moa groups. I tend to do well at those ranges with my eotech(. I think at least)

    It takes a lot more effort to get those hits with a dot at long range than it does with iron sights.

    I got a aimpoint 4moa for my wife furthest she shoots is 100yds or outside the range the furthest distance is down the bedroom hallway into the living room... for her the rds is all about simplicity put dot on goblin pull trigger. Repeat as needed.

    Just be sure your aware its not a target optic. Whatever you get, get a solid high quality qd mount you can swap the dotfor abetter taeget shooting optic down the road.

    So would you think 2moa would suit me better. I guess you're right. 250 is a little far. Lol. For a red dot at least. I just wonder if the 2moa is easy enough to pick up on quickly at closer ranges with multiple targets.

    My vortex sparc is a 2 moa and I find it to be perfect for me. I haven't put it on a ar yet (cause I don't have it built) but I used it on my cx4 and like it a lot, up close and out far. Not saying you would want that sight just trying to give you my opinion of 2 moa red dot.

    I have shot longer ranges for a few years and even the basic Mil-Dot, at 800 yards covers a generous portion of the target. It's annoying when you are trying to really put rounds in the right place.

    Now with an AR, it's more about an initial full body hit, with a couple of follow up hits as needed to subdue (read: END) the threat.

    A 4MOA dot is going to be awesome room to room or across the street to the mook behind the old rusted out Buick. But if you have to shoot down 3 city blocks at a partially obscured target? Not so much.

    2MOA is going to be much more forgiving, especially on man sized targets, but far from perfect for putting rounds in a tight formation.

    It comes down to application. Are you really building a CQB weapon that you want to stretch to 270 yards? I would honestly suggest an EoTech with their 4X magnifier that can be added and removed in the drop of a hat. ;) Great set up, but expensive.

    LaRue makes a quick mount that returns to zero with two levers that allows you to pull a glass optic and replace it with a heads-up, CQB style when you need to go close. But also expensive.

    It comes down to what YOU want for accuracy and what YOU are willing to pay.

    I have an EoTech on my 18" Larue with a set of flip ups from YHM if I lose battery power because of the EMP fired by the space zombies. :eek:

    But I also have a take down bolt gun that fits in a backpack if I need to deliver a punch at range. ;)

    To each his own, just make sure it works for you.
