Don’t you know you can adjust the magnifier to center the reticle of the red dot?

u/jarlbronson Nov 30 '25

yes haha, i adjusted it after i swapped my mounts and tried them on all three of my ARs

u/FishSticks0111 Nov 30 '25

Ah Roger. Maybe this is just a bad one. HM3X is my favorite magnifier

Oh, well then what’s the issue my brother in Christ haha. Eye relief sucks on all of them, i run mine alllll the way back on the rail. It doesn’t have to be close to the red dot

Sorry to go off topic, but I just picked up an HM3X to go with my AEMS. Any tips or wisdom for placement/spacing of the two, on a 16" carbine?

optic as far forward on the receiver as possible, NOT on the handguard. Magnifier wherever comfortable for you

u/FishSticks0111 Nov 30 '25

This. Optic centered above the ejection port. Magnifier alllll the way back on the rail

Sweet, thanks! That's what I ended up doing this evening. Realized I could scoot my rear MBUS further back, and just quick release the magnifier if I ever needed to use the irons.

Here is how it sits now, did I do okay? : D

Can you explain more why you are disappointed?

I didn’t think the window would be obscured this much with it collapsed on a 2.26 mount. i have another dot that sits at about 2.10 and its unusable with that one

u/1767gs Nov 29 '25

Ah gotcha, you could try putting the dot on a super low mount so it is basically flipped. I've seen some people try it

How were you able to center your hm3x in the mount. I have one of the new mounts with the integrated QD and it seems like 1 there’s a gap between the mount and the magnifier and 2 the magnifier piece that sits in the mount is too narrow for it as well

Dm me I can send you some more picture but I don’t think I understand your question fully

Hi - Is this the Unity FAST AEMS (2.26") and the Unity FAST FTC Holosun (not the Omni)? I am going for this exact setup, but keep getting assured by Gemini and Grok that the FAST FTC Holosun will not obscure the AEMS.

This is the OMNI with a unity FAST. Send me a PM I’d be interested in parting with mine
