I just ordered an Eotech 512.A65. I'm hoping it will be reasonably precise for work out to around 250-300 yards. I had an Aimpoint M3 with 2 MOA dot, but gave up on it and went back to the iron sights since the dot just covered up way too much of the target. My hope is that the Eotech with its 1 MOA dot will better than the Aimpoint. All I'm looking to do is land reasonably consistent hits on 12" steel plates at 300 yards. I can do this with the iron sights, but I'm looking for something that will still allow medium range shooting, but might be a little faster in up close and low light shooting than irons. |

At 300 yrds, Here is something to think about though, with a 5 or 6 MOA dot, I sight in the TOP of the dot at 100-200 yrds, that gives me about 5 or 6" of drop compensated sight at 400-500 yds......make sense? |
Sorry Doctor, but i didn´t really understand the thing, why you don´t hit the plates with an 2MOA dot but hit it with iron sights, where the front post is much bigger than 2MOA??  I think you hold under the target with the irons and not on the target, right? Why don´t you this also with the Aimpoint point?? When you don´t hit it with a 2MOA dot, then you won´t hit it also with an 1MOA....

Simple. The dot on the Aimpoint always appeared fuzzy around the edges and had a tendency to bloom regardless of what brightness setting I had it on. Not a good thing for longer range work. I was not impressed. All I know is, the front iron sight never appeared blurry.  Problem solved. As I said, I understand the benefits of an optic for speed work at close ranges and its usefulness in low light which is why I decided to try an Eotech. If it doesn't work, then I guess it's time to go back to my A2 style uppers and the irons.

 I like you..... (In a Non Navy sort of way,,,,) It's a CQB optic.... I don't see my 4MOA Aimpoint dot covering anymore of a 16" steel plate at 300 yds then my front sight post does.. But then using a Red dot sight at the range is not really the right tool, but will work depending on the skill level of the nut behind the trigger..... |

I often use an EOTech at a local range. The range itself goes out to 700yds. I have the EOTech and iron sights both zeroed to the standard US Army 25/300 meter method. I get pretty consistent hits on the dot at around 300 yards, standing unsupported, against what looks like 19-inch steel plates. I guess each shooter would have to figure out what works for them, but for me I get consistent hits at around 200 yards if I hold a little low (it looks like about 3 to 5 MOA). It is okay at around 400 yards if I hold high by a similar amount, but my grouping starts getting really big (standing). 400 yards and out is when it is time to swap in the ACOG and rest the rifle on something stable. (Keep in mind most of my numbers are approximate eyeball measurements; I haven't gone out on the range and measured everything.) I hope this is at least a little helpful. |
HUH??? "1 MOA" is a Minute of Angle, or a sixtieth of a degree (1/60 deg.). It translates to 1.047 inches for every hundred yards' distance (so 2.094 inches at 200 yards, 3.141 inches at 300 yards, and so on). This measurement is best for shooting because true rifle accuracy at varying distances correlates very closely with simple multiplication/division using the MOA rule of thumb. Here's my understanding of the various dot's. YMMV, this is only based on my own experience from my own point-of-view. A 6 MOA dot is almost 19 inches at 300 yards, and thats discounting any starbursting of the dot (that depends on several factors) which can make it seem like a much bigger dot. The problem with your 2MOA Aimpoint may have been too high of a brightness setting or degrading eyesight (I have myopia [nearsighted], so when I'm undercorrected or uncorrected dots starburst a LOT. Remember, it's focused at infinity, so unless your eyesight is perfect or you're corrected to 20/20 or better, you're at a disadvantage). I have a similar issue on my EOTech where I need to turn down the brightness a little for percision-aimed shots. A 1 MOA EOTech will be perfect for your purposes, that large ring will make it very easy to locate the dot and the small dot will only take up a quarter of the diameter of your 12" gongs (especially at lower brightness settings, which I prefer to keep starbusting to a minimum and keep the dot sharpest for distance targets). A 6 MOA dot is very convinient for long shots (100 yard zero with top of the dot is very close at 300 to the bottom of the dot with 5.56NATO), so it's up to you what you'd like to sacrifice (slower with distance shots, or inconvinience of a fixed zero [so you'll need to learn holdover with varying distances]). If you go for the large dot, run a ballistic calculator first with the load you're planning to shoot most from the rifle and match the trajectory to a dot; I got an excellent comprehensive excell-based calculator from the Maryland AR15 Shooters' Site, that gives everything you need in MOA, just punch in all the variables. |

The problem I run into with red dots at range is target identification. Sure, I can get hits on a target at 200 yards with an Aimpoint, even group with it ok. My problem is finding targets that aren't high contrast/bright colors when they get over 150/200 yards out. The reason I favor a low powered scope (3.5X/4X) is that I can find the target faster when it gets out there. At CQB ranges, of course, a red dot is better/faster. Which is why my house gun wears one. BSW |
