Trijicon TA33 owners

[C4IGrant]

Those of you that own this optic, how much eye relief do you believe the optic to have? I measured the ones we have and came up with under 3 inches of eye relief.

Not an owner but I'm always curious about interest with eye relief on an AR. In your opinion, what is a desirable number and why?

I like 3" myself so you don't have to shoot nose to charging handle if you don't want too.

My optics experience w/the AR is limited to an Eotech, with just a couple of forrays into shooting someone else's scope-equipped carbine, so I don't have much experience. At least with AR's, but I have many rounds down range with my bolt Swede gun. But I started w/irons and adopted a NTCH hold (or very close) and that's what I've become comfortable with. When I try to use the same hold on a scope-equipepd carbine, it doesn't work unless the scope is shoved forward with extension rings/mounts.

In all honesty, I just never understood why "longish" eye relief is considered so desirable when in order to use the optic, you have to then pair it with specialized mounts to shove it forward. AR's don't recoil much so in my mind much of the eye relief is wasted. Or alternatively, you need to adjust your cheekweld and move your head farther back on the stock, but that just doesn't seem natural to me.

Most all tactical type scopes have between 2-3" of eye relief. There is only one that I am aware of that has more than that and that is the Trijicon TR21. This optic does require a special mount (LT SPR-EER).

I believe that 2-3 inches of eye relief are desirable so you do not have to always be on top of the charging handle.

That was what I was thinking, 2 - 3" is plenty and 2 - 2.5" might even be optimum given form factor limitations of flat top real estate, scope tube lengths and lack of recoil for the cartridge.

To awaken an old thread... (as I have been researching the TA33-8)

According to Trijicon, the EYE RELIEF for the TA33-8 is only 1.9". Only .4" better than a TA31... :confused:

Eye Relief (in) 1.90

Grant and others have commented that it is more like 2-3" of eye relief...

Which is it?

You know what I just realized- that TA33 looks damn nice on a carry handle. Seriuosly.

Grant- call me!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

[PALADIN-hgwt]

It was my understanding that eye relief can be checked by pointing the optic at a bright light source, and holding a piece of paper at varying distances from the occular lens. The point where the light "dot" is the smallest should coincide with the correct eye position. When checking my Leupolds and Weavers the distance seems to correlate with the published specs fairly well.

[SuicideHz]

that will definitely get you close but you have to take into account your eye's lens.

aim the sucker at the sun and have your friend measure from the lens to your eye!

1.6in closest and 2.7in farthest for me, so my cheekweld is roughly 2"
thats just me though.

The compact ACOG in a carry handle is a very nice setup IMHO.

Gents,

I'm considering a TA33R-8 for this carbine

http://i32.tinypic.com/9fr483.jpg

Got a few questions:

1. The above carbine has a 14.5 Noveske midlength bbl. Does the FSB will interfere with this scopes image? I dont want a small blurry shadow in my sight picture. I know that I'll have to remove the Larue BUIS and install a flip one (Troy) but I dont want to mess with the FSB. Any one here have firsthand experience with a midlength sight radius and the TA33R?

2. I shoot mostly with both eyes open using irons and/or the Aimpoint. So, is it possible to easily focus the chevron reticle with both eyes open?

I really like the Aimpoint, but want to use it better with a LMT 10.5 upper I have. Also I think that some magnification will be of great benefit to "enhance" the capabilities of the Noveske SS bbl.

As always, any help will be greatly appreciated as I have no way to try for myself an acog locally.

PS. Grant, sorry for the hijack :rolleyes: I guess my questions may help other members as well and dont wanted to start a new thread :)

On a carbine length upper, the FSB is virtually undetectable with the TA60 mount. I would imagine a mid-length should be no different.

2. I shoot mostly with both eyes open using irons and/or the Aimpoint. So, is it possible to easily focus the chevron reticle with both eyes open?

Absolutely, it will be a little different than an Aimpoint, but you should be able to adapt very quickly. My g/f who has never shot anything other than irons and an Aimpoint was able to adapt to the ACOG in no time.

I am very happy with my TA33, I am willing to bet you would be too. As you stated I too think the magnification of the TA33 will take better advantage of the platforms capabilities.

I think that the TA33 is a good fit for that weapon.

We also just got a fresh batch of TA33R-8 in stock! ;)

Is there a "kill flash" for the TA-33? or does it use the same one as the traditional compact ACOG?

Yes and we have them in stock. :)

[Gutshot John]

cool...which model number and ill order right now ;)

[decodeddiesel]

Grant I don't see them on your site, could you directly link it?

[Gutshot John]

Oh and by way of answering the initial question...I'd say the ER on my TA-33 (.308) is at least 2" and a good way to 3" it's definitely longer than the specs suggest.

I love this scope. I have it mounted on a DSA FAL with G1 barrel. It's a great general purpose optic.

My interest is starting to peak with these.. I'm starting to contemplate selling my TA-11 to fund one of these.

Is the Chevron the only reticle option??

I like the Solid Triangle of my TA-11, but I think I could live with a Chevron.

Anyone put a Flip cover on the obj to help out with the BAC??

[decodeddiesel]

Yes I tried it. However I found with the limited FOV of the TA33 it was really not necessary. This sight is very fast, even at close range (10m or less).

The TA33 series only comes with the Chevron reticle. I prefer this reticle as it allows more light and target to be passed thru.

I don't have exp. using them but I handled byg the amber and red at a funshow in Indy this past winter.

Amber was very bright but it didn't quite make up for the fact that it seemed a lot of similar colors were around and it started to blend in.

The red was not as bright but just as bright as any other ACOG I've seen. It was easier to picku up quicker for me.

The reticle seemed small but that was because the FOV was so big. It didn't feel like I was looking through an optic.

I'd have one if I could afford one now.

As stated above, technically the eye relief is 1.90" when measured. The actual usable eye relief is more like 2-3". This is common with most of our ACOG's, the stated eye relief is shorter than the usable eye relief.

I always think of Trijicons eye relief estimates like SF's Lumen output listing. SF lights typically have about 10 Lumens more than listed and Trijicon optics have 1-2 inches more eye relief than what is listed.

I agree, the eye relief on my TA33-8 is much more than 1.9" and is very forgiving. This makes it much more forgiving, easier to use, and faster than the TA31 which I had previous experience with.

[eightmillimeter]

I just mounted the 33R-8 in the TA60 mount on my midlength goto rifle, and can say that the setup is right on. Someone earlier (sorry I forgot who it was) was wondering if the FSB on a Middy would interfere with sight picture. I found that when I was "nose on charging handle (right about 2" eye relief for me) that there were no issues with the FSB. When I went back to about 3" which also works well and is more comfortable for me the blur of the front sight started creeping into the scopes field of view. It wasn't bad, but I am anal and am going to go to a flip front to alleviate this. Also it states in the manual that Binden Aiming Concept does not work for cross-dominate eye shooters and they are right, to use this guy correctly I am forced to close my left eye before I break the shot.

Grant,
The only thing about this thing I don't like is the carry handle open sight tunnel under the scope and the TA60 mount being so high. What are my options if I want a lower mount,,,is the LT mount actually any lower? It looks like it might be and it would be worth 95 bucks to me if that were the case.

From what I understand yes it is lower. I have read that it may not be the best idea to use if you do not have a flip-up front sight as it is an "absolute co-witness" where the TA60 mount is more like a "lower 1/3rd". Obviously magnified optics don't co-witness diddly squat, but the FSB will interfere more with the sight picture, and it is the best way to explain it. :D

The LT mount will be a little lower.
