Trijicon TA31F Reticle Blurry?

[crazy_frank]

Hey guys,
I just bought a TA31F on ebay. It seems legit, I'm not worried about it being a fake. But, the reticle will get blurry sometimes, i mean just a blur of red. The fiber optic tube does not seem very bright either. The guy listed it as a month old, (which i am kind of doubting at this point). Furthermore, the optic does not include any of the original documentation or warranty card, just the scope coat, and the case (he took the foam out and used it as a range box). The left side of the optic has what appears to be brass markings, like someone was raining brass on it. Wanted to gather your thoughts. I am pretty sure i;m gonna send it back and get a refund at this point. BTW i paid 875 for it.

Mount it to the gun and makes sure you have proper eye relief. Depending on the distance of the optic to the eye sometimes the reticule will look blurry. Also have someone else look through it also. I have that same issue with my TA35F until I got it mounted to my gun.

do you wear prescription glass ?

No my vision is very good. I'm very used to scopes as well so, I know it's not just me.

Thanks for the input, I thought that as well. I tried holding the optic at various distances from my eye. I went from 1" out to 4-5", it actually got clearer the further away I got. I thought I might be contorting the parallax based in my angle, but that doesn't seem to be the case.

Ill have to mount it like you said and see how it does.

Do you think it is a decent deal for 875?

It look real to me. It sounds like you have a stigmatism in your eyes. ACOGs do not have an adjustable diopter so it can make it hard for some shooters to use.

I have astigmatism in my dominant eye and I initially noticed blurriness in my TA31 as well. However this was at close distances and with my other eye closed. If I opened both eyes, the reticle came into focus. Another thing is if you move your face around while looking into the scope, you'll notice the reticle will blur at different angles. There seems to be a sweet spot when it comes into focus. This all close range though. At longer ranges for me, it's instantly clear as soon as I bring my sight to my eyes

This + Take it outside... the optic has a fixed parallax setting...

If you try to look at stuff too close (like in ur picture) your eye is either going to focus on the reticle or the image you are looking at. Try looking at something outside at least 50-100 yards away.

If it only gets blurry sometimes, then the issue is either with your eyes or the environment that you're testing in.

This is definitely a parallax issue. Not an issue in the sense that something is wrong, but an issue in understanding how parallax works in a scope.

Parallax is the distance at which the scope's focus point is set at without changing the depth perception of your eye. If you were to completely relax your eye, your target would be perfectly in focus at 100 yards (on this scope), as well as the reticle. Your eye adjusts for the rest of the distances. Now the issue with the reticle happens when you focus your eye on objects within the scope that are close, such as the window in your picture. In this case, your camera's focus is set on the window. Since it is well short of the 100 yard parallax setting, the reticle is almost imperceptibly blurry. However, if you were to bring the camera's focus point further past the window, you will notice the reticle get clearer and clearer as you approach the 100 yard mark. After 100 yards, you've effectively hit infinity for reticle clarity, and anything your eye focuses on past that will still be in focus.

Now if you have a scope that has a parallax adjustment, you can adjust it for the distance your target it at, and have a perfectly clear target and reticle simultaneously at any distance. But you typically only see this in higher magnification ranges. Its not as critical in lower powered scopes.

It doesn't appear that there is anything wrong with your reticle. The only other issue of blurriness is if you attempt to view the reticle when it is on our outside of the border of the exit pupil, but this is definitely not the issue shown in the picture.

Hope this helps, and congrats on your purchase!

I had this issue when trying to do dryfire practice at indoor distances. (think reduced size targets less than an inch in size at 7-10 yards). Not only can the reticle be blurry, but the target tends to be blurry as well, especially when you are using indoor lighting.

Take it outside, and it's 100%.

Of course, if I take my glasses off, it doesn't matter what I do, the reticle is a big blurry blob.

Make sure you are focusing on the target and not the reticle. If the target is clear, the reticle should clear up as well.

I can't see that reticle in that pic period. Maybe it's the parallax
