Rmr help

[SDBlaster]

I'm looking for an RMR to put on top of a 3x acog I have and I didn't realize there was 50 different options from 12- 1 moa, dots, triangles etc... Can someone explain the differences from the 12 moa to the 1 moa. I get the obvious difference but not sure how that will translate onto the optic. its going onto the acog for close range shooting and would like to be able to use it for pistols as well; thanks!

MOA (Minute of Angle) is an angular measurement. A dot that is 1 MOA in size will cover an circle of 1.047" or to simplify things approx. 1" in diameter at 100 yards. Likewise a 12 MOA dot would cover a circle approx 12" in diameter. Since it's an angular measurement, as you point the dot at something further away, the dot will cover a larger area and as you move in closer, it will cover a smaller area. At 25 yards, a 1 MOA dot will cover a circle that's approx 1/4" in diameter.

Obviously, a larger dot will be quicker to see and acquire than a smaller one but will be less precise because it covers a much bigger area. At 25 yards, the 12 MOA dot will cover an area that's approx 4" in diameter.

Thank you

I run a 6MOA as a secondary sight, and I would say its limit is a 1/4 sized IPSC steel at 50yds.

You plan on swapping the rmr from acog to pistol back and forth? Why
