| I went to zero my MRO on my CZ scorpion and even after cranking windage all the way to the right, my POI is still left. Does anyone know if trijicon is able to work my sight so I can get more right adjustment? Anyone else experience this? |

Yeah somethings wierd. Check your mounting platform.
Can you see the dot move when you crank the windage? I think it's got like a 70 MOA adjustment range I think. Also not trying to be an ass, but are you adjusting it the correct direction? I see people do it fairly regularly. |

The dot does move when I crank the windage, and it's definitely going in the right direction.
I think you're correct about the muzzle device. When I got the scorpion, I attached a manticore 3 lug mount. I haven't used a suppressor with it due to the POI being so far off. I'll remove the mount, reinstall my flash hider and try again. Now that I think about it, that seems pretty likely. |

Think you need to change your thread title. You don't have an MRO issue, you have a rifle issue. Truth. While not a fan of the MRO, (and hopefully its early issues are now resolved), adjustment range has never been an issue with it. It's got to be the rifle. My guess is that putting a different red dot on it will still produce the same problem. |
|
I'm curious, have you sighted in your irons before you changed muzzle devices and did you zero your sights after?
My scorpion out of the box was dead on accurate at 25 yards. I installed a manticore 3 prong muzzle device and had no change in POI, sighted in a PA red dot in no time. |

Are your iron sights now zeroed? Did you have any trouble with the rear sight being maxed out? Yea the iron sights are zeroed and they are quiet a bit to the right without much room left. I would have thought that the MRO would have more of an adjustment range than the irons. Another weird thing is that I put my friends aimpoint on top and the POI was about 8 inches right |

Alrighty further questions, not trying to insult you OP. Is this a pistol configuration or sbr? Has this barrel ever been removed? Has the shell been removed? Has the barrel been rethreaded? Anyone else have issues with your scorpion? No problem. Just interested in figuring this out so any help is appreciated. It's an SBR Barrel has never been removed Shell never removed Barrel not rethreaded Everyone who shoots it gets same results. Thanks! |

I have an MRO and have had zero problems getting POI to match POA and it didn't take more then 1.5 turns of elevation out of the box. Windage was almost spot on out of the box. I have read all of the posts to get a complete picture of what you are dealing with and I would try two things. I would mount the MRO on an AR (a friends AR if you do not have one) and see if you can zero it without much adjustment. I would then try a different red do on your Scorpion and see if you have to dial it way right to sight the different red dot in. Depending on the results your barrel may be way off in relation to your top rail.

| I did a quick test with the MRO. I mounted it on the scorpion and 2 ARs. I looked directly down the line of the rail through the MRO. I then adjusted it all the way to the left and all the way to the right. When I turn it all the way to the right, the dot is just left of center on all 3 rifles. When I turn it all the way to the right, the dot is almost to the edge of the field of view on the right side. It seems that the adjustment range on the MRO is nowhere near centered. I will take some pics tonight. |
| So I ordered a 3 ft rod to test concentricity for my suppressor and just got it today. I put it down the barrel of the scorpion and it doesn't seem to have left or right orientation at all. Straight down the middle. I put on the 3 lug mount and the rod looks pretty center through the mount. I have no idea what's going on. |
| Just an update. Gun still shot left without muzzle device. Sent the MRO back to trijicon to see if they could give me more right windage and they seem to have just thrown a new one in the box without addressing my concerns since this one still has an off center windage range. Don't know where to go from here. |
| I did notice one thing when I got my new MRO. The instructions warned against running the adjustment hard against the stop. I don't know if you have done this in your troubleshooting. Whatever, I had no trouble sighting mine in at 50 yds on an AR. If your rear sight is hard right, it does confirm that the gun shoots left. I would GENTLY bottom out the windage to find the mid-point. Fire three rounds like that and see where it hits. Give it about ten clicks and fire three more and see if the POI is responding. Sometimes optics are tight and need a shock before responding. Keep in mind that the reticle moves Left when you turn the turret in the Right direction. This forces you to swing the barrel right to get the dot on the target. A dot or reticle works like a front sight in that respect. |
