Ta31ecos reviews

[ReconArtist]

Just curious how people like the ta31 ecos. Anybody get it and decide it wasn't for them? Looking for a general purpose optic for 0-500m shooting. Thanks.

I love the ACOG.

The optical quality is excellent and its extremely rugged.

With a RMR on top you are good to go for extremely close ranges as well.

I've got the that exact model and love it. I relocated the RMR, it sat too high for me to use accurately on top of the ACOG, which helped dramatically. The fibr optic is sometimes TOO bright, so I always keep a roll of electrical tape with me and cover as needed. Just make sure you use the cheap stuff that's not too sticky, or else you'll leave residue on the fiber optic tube. I've never tried to shoot it out to 500 yards, the best distance I could accurately shoot with it was 296 yards at a squirrel that was just shy of our 300 yard steel target.

I love mine. Out of all the ACOG reticles, my favorite one is the crosshair. Even though people say ACOGs aren't meant for precision, I could shoot 1MOA with mine all day if I cover up the fiber optic tube.

I also like being able to switch to a more heads-up position and use the RMR.

I should also mention that the stock ARMS mount that comes with it is actually really good. I usually replace my optic mounts with Larue but didn't feel the need to with this one. I can take the ACOG off repeatedly and it holds its zero every time I put it back on. After a few years, the levers haven't loosened up and are just as tight as when I first got it.

That's awesome, thanks for the response. Does anyone know if the green reticle is any different from the red? Thanks.

[teflondog]

The TA31ECOS uses the same crosshair reticle regardless of whether you get it in green or red. If I could do it all over again, I would have gotten the green reticle since the tritium is brighter than the red in the dark.

Can someone verify that the tritium illuminates a much larger portion of the reticle than the fiber optics does? I saw a video review indoors and the illuminates portion was huge compared to the examples I've seen like this one.

I had one for a few years, the portion shown as illuminated in that picture is accurate from what I remember.

Okay, I'm thinking that may potentially be an older model. Did yours come with a docter red dot or an rmr.

Its a bad *** optic. I have the green crosshair and love it. I like that it contrasts with the red dot in the rmr. Super clear glass, and bdc holds work well out to 500-600 yards. I believe it is calibrated for 62gr out of a 14.5" bbl but anything close will work just fine.

The chin weld to use the rmr takes some getting used to but it makes for super fast transitions once you get the hang of it. As others have said the included mount is solid and easy to use and returns to zero well.

One thing to consider is how you want to zero it. Typically RDS is zeroed for 50/200 and acogs are zeroed at 100. That's how I have mine set up, but you do have to consider that the POIs are slightly different if you go that route. I could also see an argument for consistency and zeroing both at 100. Also consider you have a very high 3.5" or so height over bore when using the rmr so that's something to account for in the trajectory as well, albeit minor.

The one downside to this setup I will point out is that its not NV compatible. But that still wouldn't stop you from using an IR laser.

If you have the means and want a dead simple, rugged optic that just works, its a good way to go. And the FDE color is a bonus.

I am running the green crosshairs TA31 on my SCAR 17. I love the reticle.

On mine, the tritium illuminates the exact same area as the fiber optic. Mine was bought in 2013 and came with a Trijicon RMR instead of the Docter.

[John03]

I wouldn't hesitate to buy one, its a really great piece of gear for a carbine. The reason I bought mine is because I used several of them while I was in the Marine Corps, beat the crap out of them and they never failed.

Sorry for the late reply, mine had a docter red dot.
