View Full Version : ACOG experts. Is this fake or real
Before someone says call trijicon I have. They told me that with it being that old they don't know without sending it in. I bought this a few years back from my manager. He bought some old sp1 that had it mounted in the carry handle and asked me if I wanted it. 600 dollars later it was mine. It has tritium in it. Its dim but there.
Recently someone asked me if it was real. I said yes. The thing that makes me wonder now after looking in depth is there is a dovetail for a front sight which I've never seen before on a ta01 acog. I've put this optic through the ringer the last couple years and it holds zero and has not broke. The only thing I've noticed is the elevation turret is not very positive. But with it being this old and seeing all the battle scars on the optic I can understand

Reticle is a ta01 reticle. This is not a ta01nsn unless it was a preproduction run of them. It lacks the machined tabs on the rear eyepiece for a buis

It looks real enough to me. That is old with a 4 digit serial number.
Since the tritium is kaput, you need to send it in to Trijicon anyway for a recharge and they can give you a definite answer.
Pass. They told me 530 for new tritium. I paid 600ish for the optic. Its bright enough to work at night. But at night I have a pvs14 and a peq-2a
That's real. A possible solution for the elevation turret being a bit loose / sloppy is to dial it up (to the left) quite a bit, then give the scope a good thwack with the palm of your hand from the bottom. Dial down your elevation again and see if there's better pressure / engagement on the turret. This has solved the same issue on a few very old TA01 NSN's that have made their way onto M4's when we're running low on optics.
Thanks man ill try that. I wondered if that might do it before but never tried. It just seems to lack a positive "click" but ill give that a try next time I can make it out to the range.
Yeah, it may or may not improve the physical feel of the adjustment.
Either way, just remember to give the ACOG a few taps / light wacks near the turrets after making elevation / windage adjustments during zeroing. This will make sure that your adjustments actually take and prevent you from chasing ghosts around the zero target.
ACOG's are quality, tough optics...they just have that one quirk.
Yea I was taught to give them a whack after adjusting them. I usually smack it with the back of a magazine. Its always held zero pretty well. I handload so every now and then ill have to change elevation a bit based on loads and outside temp. Windage has always been pretty straight on though. I've got it mounted on a 12.5 and the BDC works well enough to hit man sized steel out ti 400 yards
I appreciate the feedback guys and reassuring me that it is real. Its mounted on my go to gun so I got a little worried when the question arrised if it was fake or not.
It's not automatically a bad thing, but there's no need to use an implement.
Just give it a solid thump with the heel of your hand on the WINDAGE dial (with the cap ON) to set the prism.
Be verrrrry careful when taking either dial to it's limit in any direction. There aren't any positive stops on your model, and it's possible to render the adjusters ineffective. It'll literally unscrew, and it requires a trip to Trijicon to fix.

Good point about going too far. Sometimes I neglect to add disclaimers with the assumption that they're common knowledge. On a public forum it's probably best not to make that assumption. So thanks for pointing that out.
Now, the reason I said to dial up the elevation turret then give it a whack from the bottom is for the purposes of shaking the springs that provide positive pressure on the dial. I've never disassembled an ACOG, but Trijicon recommended this method when a few older ACOG's that had been sitting a while exhibited a similar looseness in adjustment. It seemed to work. After dialing the elevation turret back down toward zero the clicks were much more positive and stiffer overall. Again, I've never had an ACOG torn down, but it's almost as if the springs were on a ledge and needed to be knocked free to again engage the dial.
I'm only speaking to the thump in regard to zeroing and the like, to set the prism and prevent adjustment-loading; not as a general reset for more positive clicks on the adjusters themselves.
I've not run across that aspect; the Corps' RCOs are recent enough that they haven't tended to sit for long. Broken according to the "Fable of the Three BBs," yes.....:D
Looks real to me just an oldie
