| Looking at getting an RMR 07 with the 6.5 MOA dot. From what I've read this is supposed to be the best size dot size for handguns. My only hang up is I still would like the capability to take shots out to 100 yds if need be. I am physically capable of shots with a handgun that far. Yes, I do realize I probably won't be engaging at that distance, but then again it's always those laughable scenarios that bite you in the ass. Hell, Most department stores are 100+ yds. This is why I keep going back and forth to the RMR 06 with 3.25 dot. For you guys with experience on RMRs, what are your experiences with the range capabilities of your dot sizes. Am I limiting myself with the 6.5 dot? Is the 3.25 dot that much harder to pick up? thanks |

I put one of the new(er) Vortex HD Razor red-dot's on one of my pistols. I was originally going to go with the 6-MOA, but ended up getting a great deal on a 3-MOA model. The pistol is used for 5 to 25 yard plinking, so I do not have any issue with the 3-MOA. The 3-MOA is still big enough, at least for me, to pick up and acquire sight-picture rather quick, so I do not have any regret of getting it.
In your hypothetical situation, engaging a person at 100 yards, think about it this way. 6.5-MOA would be a 6 1/2 inch circle at 100 yards, smaller than that of a human torso. It may not be the most accurate option, but I would still think it should be doable. If worse comes to worse, RMR's hold their value pretty well. So you could get the 6.5 and give it a try. If you aren't satisfied, you could probably sell it / trade it for a 3.25 model with little to no out-of-pocket spending. Just another way of looking at it. |

That's a big ass dot! No opinion though. This will very somewhat by shooter, but I calculated the white dot on a Trijicon front sight as being ~13MOA. A 6.5MOA dot would be about the same size as the tritium vial in said white dot. At 100y the average human torse is 18MOA. At 200y is it still 9MOA, meaning a 6.5MOA will not completely cover the torso at this distance. Those you you capable of making two hundred yard head shots with your side arm will want the smaller dot. When I built a open Glock several years ago, I put a 3.5MOA Docter Sight on it. I never had any trouble seeing or tracking the dot, so I cant say 3.5MOA was too small. Hand I though about it, I would have gone with the 7MOA version. ETA: One MOA at 100 yards = 1.047" |

One MOA at 26" = .007562"My front sight is .125" wide, or 16.5 MOA.The white dot on this sight is blacked out but is close to .094", or 12.4 MOAThe glass of the tritium vial is .063", or 8.3 MOALonger or shorter arms will make the apparent MOA size change.For example with a 22" line of sight, the functional size of the same front sight become 19.5, 14.7, and 9.8 MOA.This is because 1 MOA at 22" is .006398" in stead of the .007562" it is at 26" Quoted:

My standard for 200yds is just being able to ring torso-sized steel, 2 hand, standing unsupported. I'm not going for head shots. If the target was smaller or partially obscured my problem would probably be seeing enough of what I need to see to align the dot on target -- the size of the dot (3.25 vs 6.5) is probably not the issue in that case, if that makes any sense.
No problem getting 200yd torso hits with the RM07 (6.5MOA) on my Glock 19. The Docter III 3.25MOA is only slightly easier (ATOM mount lets me try both.) |
