Outstanding thread. Im surprised by the MRO performance. That Parallax is extreme.

Any chance you did the parallax test on a T1? Parallax was supposed to be a major improvement in the T2 over the T1.

Truly outstanding thread. Thank you for taking the time to run the tests, record the info, and then share it here.

Quoted: Eric Dorenbush, Green Eye Tactical, did that exact test for us in north Texas a few years ago View Quote I remember that test, but it was all dry with no live fire like Molon's. IIRC, the T1 had around a 4.5 MOA shift at 50 yards in that test, and the MRO was 7.5. The Eotech did best at a little over 1. |

I don’t post often, but your work is always worthy of praise. Excellent post as usual.

Thank you Molon. I may add to the overwhelming derp here but I really keep showing up for threads like this
The T1 may have parallax issues, but I haven't had any problems using mine to make consistent hits at 700yds on 4moa targets (16" M193). I'd be really leery of using an MRO though in case I had to be in weird positions. |

While I believe and like the parallax stuff, I disagree with shooting reduced targets and comparing them to long range shooting. if the target is 6 inches or 3 inches at 100 yards and the rifle is shooting 1.5 moa all hits are going to be 1.5 moa at 100 yards. just with a smaller target. Even if you adjusted the dot to be zeroed at 600, you would not get the same 1.5 moa ( 9 inches roughly ) group at 600.
In my shooting with red dots, I found smaller targets at 100 where easier to get smaller groups. Just turn down the brightness and center the target in the dot, vs centering the dot in the target. Putting a 1 moa target in the center of a 2moa dot, is more accurate than trying to center a 2 moa dot on a 18 moa target ( shoulder width ). I under stand you tried to compensate for this by shooting at the head to eliminate some of the reference on the target. |

@molon
I don't remember a thread I have enjoyed as much as I did this one; thank you! |
|
Well done Molon. I have the same ML2, and though I have never tested it like you, I get very reliable hits on 12x12 plates out to 250, less reliable bit still decent hits beyond that.

So what you're saying is anything other than an Aimpoint T1 or Trig MRO is GTG?
+1 for the Pro being an "affordable" and effective RDS. (Who am I kidding...most folks laugh at spending more than $200 on an RDS) |

Good thing I only use my MRO on my 300BLK pistol bc thats just sad.

Used to qual with our SRT unit with a M4 and old Aimpoint, head shots at 100m were not a problem.
That is some outstanding work you put into this thread Molon, thank you. |

Quoted: I'd like to see an MRO go up against a NCstar, or some other random Chinese Amazon dot. View Quote I suspect the MRO as a class would outperform Chinesium knockoffs as a class. Individual optics might vary, and that would be the problem. I've seen more MROs fail than PROs in organizational settings, and where far more PROs are in use, the MROs still fail greater numerically and far greater percentagewise. But when they work, they're pretty decent for what they are. Pretty reliable, pretty good, and moderate cost and lower weight/smaller size. Per Molon's test, they do seem to underperform in some ways, though. |

Quoted: A little trick I brought over from highpower competition to USAR qualification. When I'm grouping the M4/M16 with CompM4s at 25 meters, I use an aperture to force head position to mitigate parallax. I bought a 38mm slip-on lens cap from a photo equipment store and drilled a 1/8" hole in the center. https://photos.smugmug.com/photos/i-QC4bRRX/0/884720e5/XL/i-QC4bRRX-XL.jpg https://photos.smugmug.com/photos/i-Ck9LTsq/0/4c37018a/XL/i-Ck9LTsq-XL.jpg View Quote Full cowitness and backup rear irons do this as well. Also the backup irons with small apertures will reduce astigmatism for those who see starbursts instead of dots. |

Anyone who thinks you can't shoot tight groups at distance with a 4MOA dot has never tried, can't shoot, or is simply a moron.
If it was impossible, how in the holy fuck would anyone be able to consistently hit a 500+ yard target with irons? |
|

Incredible work. And your nod to “Serenity” did not go unnoticed.

What I do not understand is why Trijicon has not already dealt with this issue. It has been known for what, a decade, or is it two?
How do you spell, U-P-G-R-A-D-E? |

Excellent post, as always, Molon! Thank you for what you do. Research and information like yours is what originally drew me to AR15.com in my lurking days.
