I recently purchased an Aimpoint H-1 Micro w/ the medium (HK) mount and the aimpoint 3x magnifier in the short flip to side mount.
Larue Tactical’s website states that the magnifier will sit “slightly” higher than the optic but it will still work. The pictures on their chart back this up. The offset is noticeable but negligible and only if your really looking for it.
When mounted on my rifle however the offset is considerable, approaching 1/4". I spoke with Larue Tactical support and they had me remove the magnifier from the mount to ensure that it was the short flip to side mount and it indeed was. After that it was pretty much no impact no idea and if it isn’t too awkward go with it. I really like Larue’s gear and their customer service is top notch but I’m having a hard time not getting irritated by this.
I’ve seen USMC03’s posts on the micro w/ magnifier in Larue mounts and his look exactly as the website represents with the slight misalignment but otherwise GTG. The Medium mount w/ the short pivot mount are shown to align similarly so wtf?
I can only think of 3 options:
-the magnifier mount is jacked up (too high)
-the optic mount is jacked up (too low)
-the chart on the website misrepresents the actual alignment when utilizing a medium optic mount w/ the short pivot mount.
I’m leaning towards the second one myself and was hesitant to even mention the third as I really do like Larue’s mounts and service. Has anyone had issues with the Aimpoint Micro on a medium height mount or with this combo in general?
Are you upset because the mount doesn’t “look right”, or because the dot isn’t centered? If it’s the latter, use the magnifier adjustment screws to center the dot. If it’s the former, good luck!
The Larue flip to side mount does not have adjustment screws like the EOTech mount, where it sits is where it sits.
As far as “not looking right”. It’s not a cosmetic issue for me. This combination has a slight offset right out of the box and I was aware of that going in. The problem is the offset on the gear I received is quite a bit more than what is represented on the attached chart. There is a sweet spot that I have to look down to see the red dot, any higher or lower and all I’m getting is a fantastic 3x view of the ring around the optic’s lens. The top edge of the optic lens sits in the center of the magnifiers view.
Can I shoot with it? Sure. But If you spent a grand on a scope and the top half of the reticle was obstructed you would be kinda irritated if customer service said “if you can still see crosshairs just go with it.”
I’m not a fan of the lower 1/3 co-witness. I went with the short flip to side mount and the medium optic mount for the absolute co-witness.
I already had the Aimpoint with the medium mount well before I purchased the magnifier. Also, the short magnifier sits too low to work with the tall mount so I got what I got and don’t want to spend another few hundred buck for tall mounts. The medium mount and shorty pivot should just align as advertised and I don’t think that’s a lot to ask for $1,200.
I’m just on here to ask…Am I missing something or is something dorked up with one or both of my mounts?
I’d call LaRue and talk to them about it. You could try E-mail, but they don’t always go thru. Clearly there is a discrepancy between their pic and what your mounts are doing.
I did and sent them the same pictures as well. The fella I talked to had no idea and didn’t offer any other recommendations. I replied saying, basically, that that’s not a good enough answer but I haven’t heard anything yet. I haven’t gotten snarky for the simple fact that they have always been great to work with and I’m giving them the benefit of the doubt, but something obviously isn’t right. I know what I want them to say but I’m not going to tell them what I’d like to hear until I’m positive they’re not going to say it (if that makes any sense).
I have tossed around the idea of fabricating some kind of shim to go between the micro and the mount but I’d like to see what LT has to say about the whole thing first.
3.3 Operation procedures
The 3XMag does not need to be zeroed. However, the
Aimpoint sight used together with the 3XMag must be
zeroed so that the red dot of the sight creates the correct
point of impact.
Additionally, the 3XMag has two Allen screws which
allow the user to center the red dot of the Aimpoint sight
when viewed through the 3XMag.
Centering the dot inside the 3XMag is not necessary, but
creates a more natural feel.
NOTE: Any adjustment of the 3XMag does not affect the
point of impact. Do not continue to adjust the screws if
you encounter resistance.
The Aimpoint 3XMag, Magnifying Module is now ready to
be used.
I don’t know how much adjustment there is, as I have never had to tweak mine. Might be worth a try.
Ah, I misunderstood, I thought you were referring to trying to adjust the pitch and yaw of entire tube and ring via the mount like the EOTech version (made by A.R.M.S. I believe). It might help a little but I need to lower the entire tube straight down at least 1/8" to get my eyeball, the magnifier, the optic and the target all lined up without hunting up and down for the “sweet spot”.
There is no where near the adjustment room to compensate for that.
The adjustment on the magnifier is for centering the dot in the magnifier. It will not make up for a mechanical mis-alignment. I would check and make sure you got a short magnifier mount, both by looking on the bottom and measuring the thing. Some thing isn’t right. Same with the RDS mount.
Why Larue can’t make these thing mechanically line up perfectly is beyond me. At this price point, it should line up even. It kind of rubs me wrong that even on the chart they don’t line up. If i’m using a Larue mount on both items, why shouldn’t they be centered? Not close enough, but perfect.
I think it has more to do with when they made the Micro series RDS mounts their primary concern was getting the proper lower 1/3 co-witness. Then the magnifier’s got second priority. I’m guessing the H-1/T-1 mounts sit slightly lower than the M1/M2/M3 so they compromised in a way that the magnifier would work well with both sights but not quite perfect with the Micro series RDS.
LaRue told me NOT to get the LT-660HK unles I was running the HK-416 or another similar piston gun as the co-witness with my irons would be wrong and the 3xMag would not line up right. I would replace the mount! Did you get it new…if so they will take it back within 30 days and maybe even after if you explain your dilemma! Good luck! Great looking gear!
I can understand the co-witness issue but how could piston/HK vs. DGI/AR system effect the magnifier lining up? A flat top rail is a flat top rail. Also on their chart they are using troy BIUS not a HK diopter type sight so it appears their setup is on a standard AR platform with no issues. I suppose I should quit playing email tag and get on the phone, from what I understood, once you mount an optic you own it and it’s considered used.

But they make both the magnifier mount and the RDS mount. No reason why there can’t be more than one solution at a $700 dollar price point. I don’t want something that “kind of lines up but should work.”
If I use their magnifer mount with their RDS mount, they should play good together. Consider that buying both from Larue will cost you over $1k.
This is a huge consideration for me as I am in the market for a new optic.
I do not own an HK 416 so I can not say for sure, but the rails on the dedicated piston guns may be a little taller to accomadate the piston system so the mount needs to be shorter to achieve the same co-witness. Now as for the 3xMag, the guys are right and you can adjust it to center your dot. As for the mount…if you bought it directly from LaRue, call them and explain the situation (you are using a DI gas gun, right) and MAYBE they can work a switch for an LT-660 mount. Give it a try. Also, move your H-1 mount to the muzzle end of your upper and see if the perspective improves as their combination shows it mounted at the end of the rail on the upper. I know you probably have but check and see if your pivot mount is indeed a SHORT mount (the default one to order in the drop down box on their site is the TALL one)! Good luck!
That was the first thing LT asked me to check. I removed the magnifier from the mount and there is either a 3S or a 3T on the ring. It indeed was a 3S. I originally positioned the RDS at the far forward end of the upper receiver. It’s just as awkward to look through but obviously a little harder to draw the imaginary lines from one lens to another to see just how far the alignment is off. But whether it is fwd or back a couple rails doesn’t affect the overall function or lack thereof in my case.
I just don’t I see how mounting the HK mount on an AR platform would cause this. It will only affect co-witness if you were trying to attain a lower 1/3. If you used tall mounts with an HK diopter sight you would have no co-witness but the magnifier and the optic should still line up.
