Wild,
If using a Micro T-1 on an M4 carbine variant (whether fixed or folding front sight) you’ll want to use the the LT66X Tall Riser or ADM Micro Mount with either standard (CO) or 1/3 (SOCOM) Witness spacers. LaRue Tactical is now making a mount for the Micro T-1 that works for HK416s using HK Diopter sights. The new LT660HK Micro T-1 mount is a very nice set up for the HK416 platform. See picture compliments of EAG Tactical.

I like the look of that HK mount, FJB. The lightening holes look like a good idea, even though removing that much aluminum prolly only saves a fraction of an ounce. But I will take your advice and go with the regular tall mount.
Even with flip up/down iron sights I prefer the lower 1/3 co-witness set-up as it gives you a bit of a more “Heads up” position and field of view when viewing through the optic, as opposed to the absolute co-witness which requires you to get a lower cheekweld when obtaining your sight picture through the optic. I suggest that you go with the standard “Tall” mount.
Hah…lower 1/3rd cowitness is a chinweld for me.:o
I want to put mine (when I get one) on a Vltor VIS. I have a regular Aimpoint on there now, but for some psychological reason I can only tolerate the optic in the old place, right above the mag well. There are supposed to be advantages to putting reflex sights as far away from the eye as possible, which is certainly an option with a monolithic upper, but it just doesn’t “look right” to me. Has anyone overcome tradition and mounted a T-1 all the way forward on the rail, near the muzzle?
FJB- nice mount. It appears that the HK416 mount is right between the LaRue high mount and low mount in terms of height, is that correct? I assume the HK416 mount works on any standard flat top upper? I’ve got a LT tall mount for my T-1 on the way but really prefer a co-witness set up, looks like the HK416 might fit that bill? Thanks for your time.
jbsf3,
The LTHK416 Micro mount is .3" lower than the LT 66X Tall mount, so it won’t cowitness with standard M4 Carbine iron sights. The LT66X Tall mount is a 1/3 cowitness, but it is not as bad as you are thinking.

Copy, thanks FJB!
Can someone please post a pic of the shooter’s view through an Aimpoint T-1 Micro. Preferably mounted on a carbine with a fixed front sight base, with the T-1 set up with a lower 1/3rd co-witness. Thanks.
I would love to see this also.
Here’s the best pic I’ve seen of the T1 from a shooter’s perspective.
It’s by MFinger showing the LaRue 1/3 cowitness mount. The front sight is is a Troy flip-up but a standard fixed FSB will look the same through the optic.
Mark DOES take some of the finest pics in the industry! I can only wish my camera skills can come close! 
I find the LT 661 about perfect and also co-witnesses perfect with a PVS-14 as well along with a GG&G tall mount for the 14. Great mounting solution to say the least!

Micro T-1 on my shorty at work.
BUIS is folded down.
A little late to the game but oh well…
T-1 on LT Mount on a 14.5" LMT carbine:
how come the larue base doesnt cowitness the T1 with the FSB?
Because most LaRue customers want the iron sights in the bottom of the optics field of view. Myself included. It clears up the sight picture.
In regards to dot sights, eotechs, acogs…which is better? Do you want your dot sight to cowitness with the front BUIS or do you want the rear and front BUIS to be in the lower 1/3rd of the sight picture?
There is no “better”.
Lower 1/3 or so-called “SOCOM” co-witness gives a bit better field of view, some might say is less “cluttered.”
But many run absolute co-witness just fine, and some prefer it because it shoulders the same/uses same cheekweld as irons.
This is one of those preference areas.
I don’t mind a Co-witness when I have a flip up rear BUIS in the down position. When I use a LaRue BUIS, Aimpoint, Fixed FSB, I prefer the SOCOM (Lower 1/3)- for me I can pick up my dot/target faster with less clutter.
I prefer lower 1/3 - easy to transition to irons, yet less clutter when using optics. As with everything, you’ll be best with what you train with.
