Trijicon TR24 mount questions

[Mysteryman]

Yeah.
I didn't think so.
The magnification is closer to 1.25X

The 45* BUIS's are not going to be used on this upper. (I don't 3-gun or anything.)
As long as the ADM 30mm Recon can clear a Troy, I should be OK.

The Tr24 is a true 1x on the bottom end. That being said, you still can't reliably co-witness through glass. Its "doable" for short range and immediate threats/shots but I would be dumping the glass ASAP.

I actually like the concept of having the off-set iron sights as a back-up to the variable 1-?x scope on a patrol rifle or fighting carbine and plan to go to that set-up once a set of off-set irons come to market that don't cost outrageous $$$. Having to dismount the scope, regardless if which QD mount I am running, and flip up a set of back-up iron sights is not something I want to have to worry about in a fight.

Offset irons are fast, but I find that having to roll the rifle is something new to learn and it doesn't work in an ambidextrous capacity. If your offsets sit on the right side its difficult to impossible to lay on your right side and shoot under cover/concealment. Its infinitely difficult to shoot from your right side from your left shoulder with offset sights.

Optical failure is a very low probability, and removing an optic can be done very quickly, especially with some mounts like a BOBRO or the Scout series from ADM with a single lever.

That's been my plan for a considerable amount of time. I'm still trying to work out optimal weaponlight placement so that it's still really usable with the rifle canted if a need arises for that, but yeah, that works.

I'm willing to give up some ambi flexibility in the case of an optical failure and needing to go to BUIS - I'm already functioning with compromised capability, if I'm reduced to point shooting off the support side it's not the end of the world there, I like having persistent iron sights available in a hurry, especially if I happen to have the scope cranked to max zoom and need a quick up close sighting solution without removing my support hand to crank away at an optic.

I have had several occasions where I have been setup outside in the cold for an extended period of time, and then entered a warm structure. The optic lenses fog, and twice were covered in ice. I like the Dueck sights, because I can just roll the rifle, and drive on. Oh, and I run my TR-24 in a Larue LT139.

Wish Dueck or someone else would come out with a set of off-set sights without the rear elevation knob which I feel is useless for the application. It wouldalsobring the price down a bit.

The flip-out off-set sights from DiamiondHead look pretty slick, but think I would rather have a set of fixed off-sets. Would think Troy or DD would have brought something to market by now???

Agree 100% on the optic fogging. Cant tell you how many times I have stepped to the line for a drill when it was chilly out and just as "Stand-by" is called on the line, I let out a deep breath with my AR in the low-ready only to bring my TR24G up to my line of sight to shoot the drill and it is completely fogged from my breath

A fixed sight should be set it and forget it if they aren't built for precision use - i agree.

Has anyone tried the xs big dot offset sight?

LaRue LT-139

I have been running mine in the LT-139 for 3 years now. The taller mount was a little too tall for me. The LT-139 SPR-E is perfect for me in-terms of height and eye relief.

I think you will be very satisfied with the TR24. I am selling mine only because I am moving up to a 1-6x for a more precision/DMR type role.

Question for anybody


Do you run a backup rear site? Which backup rear sites clear?

I had a Magpul MBUS BUIS previously that I think would work. I have a Troy folding rear battlesight that does NOT fit. While it clears in terms of height when folded, it is too long to fit on the rail. The magpul fit because the site folded down to the rear (towards the charging handle) while the troy folds forward (into the scope mount's base)

What is the best backup rear site that will clear the TR24 under an LT139 SPR-E? I'd really like one with two aperture sizes, like my stock carry handle site or like the Troy that doesn't fit.

(I just installed mine today)

[nickdrak]

Troy fits all day long. Sounds like you installed your Troy rear sight sight backwards if im understanding you correctly. It should fold to the rear just like the MBUS.

I have one of the original Magpul MBUS sights mounted under my Larue LT-139 with a TR-24G. It's riding on a 6920 with a DD RIS II rail.

The Magpul sight does not deploy with the scope mounted. I don't know one that does. I have to dismount the scope, in order to deploy the BUIS. Not the best solution in the world, I know.

Having said that, the TR24 does not have batteries, and seems to be robust. I also kept the fixed FSB on the carbine as you did, and can make reasonably accurate hits to 50 meters just using the scope as a giant ghost ring.

Someday, I'll swap the Larue for a Bobro, which I could dismount much quicker. The Larue needs two mules and an ape to get on and off the rail. I'm honestly not worried about it, that carbine is third in line for defensive carbine duties.

I have seen guys run their MBUS backwards, just for the reason you describe. All my other carbines have a fixed front and rear BUIS, with an Aimpoint H-1 mounted between them.

Never forget to check the operator's headspace. lol
