My rear Troy sight wouldn’t fit beneath my new MTAC, so I moved it ahead of the optic mount. I can still get a good sight picture when I remove the optic. Does anyone else do this? It seems to be fine for “oh damn it” situations, and really doesn’t impede other functions or add any real weight.
Might as well just take it off, if it doesn’t fit where you can make use of it.
It’s highly unlikely that you’ll be able to use that rear under ANY circumstances where you’re removing the optic to do so, unless you get some freaky-deaky Dr. Moreau operation to to transplant some other species’ eyes into your head. The aperture is too far forward; more specifically, it’s too small to be truly usable when that far forward.
What mount do you have? That’s a LOT of footprint that probably doesn’t need to be there.
Two potential material solutions (incomplete based on the fact that the photo doesn’t show everything that’s going on, there):
-buy a LaRue or ADM optic mount that gives you the room you need to place the rear BUIS where it belongs.
-buy a KAC Micro, if it’ll fit under the optic in the mount you currently have.
honestly, I see several things wrong with that mounting. first, the scope mount looks really low. my Troy folding BUIS fits easily under an Mtac in an ADM recon mount at standard height and some folks even use a higher mount than that…
and I can’t tell but it doesn’t look like your mount is QD. this is not like a RDS that you can use your iron sights through if it fails. if the scope goes TU, you’re going to need to detach it, and possibly quickly, to access the BUIS…
Two things. First, what you did is plausible. Dave Lauck of D&L Sports does that. But he uses a rear sight more akin to pistol sights. Not sure how well a peep sight would work.
Second, as was already suggested, look into a different mount. This is the extended ADM and as you can see the Troy rear fits. I shoot nose to charging handle and have the eye relief I need. Not sure how the relief is on your glass.
Lose the Armalite/RRA mount and pick up a Larue/ADM/Bobro. If your budget can’t handle that you can get a Burris PEPR QD.

Thanks for the input. The mount is an old Armalite that I had lying around. I installed it so I could try out the scope. It does take up a lot of space, though, and the height and relief aren’t optimal. I was looking into ADM and LaRue for the near future.
On another note, the MTAC is really incredible. It’s fast at closer ranges and has a great reticle. I will be trying it out at distance in a week or so.
I have a commercial Leupold VX mounted on a flat top in a Larue QD mount in the last slots (in order to get correct eye relief) on my coyote rifle. Hiking around the boonies, I hate the thought of falling or otherwise disabling the optic and being done for the day (BTDT), so I sighted in a Matech BUIS in the usual position on the rifle, changed the hex head screw for a thumb screw from an EOTech base kit (pricey mod), zeroed it for minute-of-coyote at 100 yards and moved it to a forward slot for on-gun storage where it lies under the FOV of the scope. It retains zero pretty well when moved to the rear. If needed, I QD the scope, move the BUIS to the rear, and I’m still in the field for the rest of the hunt.
To the original poster: Your “rear” sight is mounted reversed in that picture.
Yes. Due to the shape of the mount it would have to be even further ahead were it installed normally.
Get a different mount!
Mounting the rear BUIS so far forward, in addition to the already mentioned problems, will make your sight radius practically non-existent, thereby magnifying any sight alignment error. Also, any elevation and/or windage adjustments are going to much more severe, due to the short sight radius.
Not to belabor the point, but I am still left with plenty of usable sight radius. It’s only a few inches less than a standard buis. I have a 13" troy alpha rail on the gun with the integral front sight at the end of it. I realize the photo doesn’t depict that, though.
I am going to get a new mount, however. I would much rather the rear sight was as far back as possible and that the optic is in an optimal position.
Thanks for the suggestions!
Ditch the mount and get a diffrent one I run the Bobro/Horus talon with a Knights works fine.
