TA02 Overview (00:00):
What we have here is the Trijicon TA02. This is very similar to the traditional TA31 that most people are accustomed to seeing with the main differences being, this is a battery powered ACOG so it does not have the fiber optic running across the top. That's just constantly pumping power into the reticle, but instead you will install a battery and then you can set exactly what brightness you want. I actually really like that about the optic. I don't have to worry about Tritium and half-life and everything that's going on there. I can literally just add and remove batteries. And then if the battery dies for whatever reason, I still have a very nice etched reticle inside the optic for redundancy. The other main difference with the optic compared to the TA31 series is the holes to mount a backup, piggyback red dot, and usually an RMR are not located in the rear of the optic, like the TA31 they're actually located in the front.
So when you take your mount—it is a specific mount you have to buy for this optic—It is actually gonna place the RMR in this front location, and we'll show how to place that. There's a lot of advantages to moving the RMR to the front versus the rear, especially if you're using night vision. And it also just pushes the optic a little further from your eye, and you can see a little bit more around it. So mounting the optic to a rifle is very simple. It comes with a standard Thumbscrew mount for Picatinny, so your flat top on your M4 whatever. We're gonna loosen those. I have a 14.5" right here. The eye relief is still about 1.5" inches, so you will be most likely based on your length of pull, of course, but most likely going to be mounting the optic towards the far end of your receiver, using a flathead screwdriver, or even pliers to tighten down the mount to the receiver. The optic runs off of a AA, so we is going to unscrew the cap and I recommend you use lithiums. It comes with an Energizer lithium, which is very nifty. Plus sign running on the inside or towards the inside of the optic.
Brightness Settings (02:05):
Set the brightness of the reticle. There is a rotating turret on the left side of the optic that has numbers one through six, and in between each number is an off position. So if you know "Hey, most of the time I'm going to be in the four position. So I'm just gonna turn it off in between the four and the five". You'll be good to go. Most modern optics have that feature, and I think it's classy.
RMR Mounting (02:27):
So let's talk mounting an RMR to the top of the TA02. So I have another one right here. And the first thing we're gonna do is we are going to remove the two top screws that are included on the optic. They ship with these screws so that the threads are protected. So if you're not mounting an optic, just leave them. You don't have to worry about them. But if you do go to mount RMR using this plate, you're gonna have to take them out. So we're gonna unscrew these. Now that the screws are removed, We're gonna get our Allen wrenches out from the mount. We have the mount right here with the two screws already threaded through. We're gonna take the square Allen wrench, and we are going to do more or less hand tight, and a little bit. Awesome. So plates installed.
Now it's ready to accept your RMR, your SRO, or other optics that can utilize a plate adapter from an RMR to that optic. There's a few plates out there that, allow you to put different optics on, but we're gonna do an RMR. So all traditional like, so I'm gonna remove the two screws they include for the RMR. Then we have an RM06, if you have a sealing plate you can use it. I would probably recommend that, but we're just gonna do this one without. Both screws are installed. We then take the Torx Allen Key. These are already Pre-loctite-ed. So we don't have to worry about that. Once again, we're gonna do hand tight and a little bit, and we're good to go. So now we have our RMR mounted to the front of the TA02, And we will mount that to this 416. Again, running all the way to the rear. We do have a rear sight, but that should be fine. And that's more or less what it looks like.
And then as far as shouldering it, the head is nice and upright. The RMR being up front makes it a lot easier to shoot with gas masks and with night vision, if you have a night vision like your, your duals on, and you have the RMR right here, you're gonna have some fitment issues. And that's why this optic with the RMR pushed in front on top is superior, in my opinion. If that's a setup that you want to go with.
Zeroing (05:09):
As far as zeroing, the optic, they come with a T.REX ARMS 50/200 meter zero target. I recommend doing a 100 meter, 100 yard zero with this optic, for the… All the MILs and the BDC and everything to work inside of it. So what I would do is take this target, try to shoot it at a hundred, if you can. And I'm just going to aim for the center of the square up top. And then I can still use the grid for my adjustments. But you wouldn't be using the offset down at the bottom to get your zero. Instead. You'll just use the top. As far as the reticles go, there is a traditional chevron, and then there's also a crosshair reticle. I personally prefer the crosshair reticle. I have a much more refined center, aiming point but the Chevron, if you're a traditional ACOG user, is obviously a good option as well.
