I was zeroing in the ACOG in heavy rain and looks like moisture went through the adjustment mechanism - the caps were off. Now there is condensation (fog) inside, how do I dry it off and is there any permanent damage. Can I keep it under the sun for a few days? Or is there a better way to dry it off? |

From what I understand my TA31 ECOS is waterproof up to 11m even with the caps off. |
Trijicon pressurizes the ACOG with nitrogen to prevent condensation and any ingress of foreign materials. If you have condensation, the seals (that I supply to them  ) are shot. Contact Trijicon and make arrangements to send it back. They should repair it under warranty. |

TA11C, low serial number, it's 12 years old. I tried to capture the fog inside, there is fog half an inch below surface on either end, plus I found obvious water inside. Apparently it's the seals that went bad and not the adjustment turrets. I washed it under faucet and I think that's what did it. No problems doing that for 12 years and it finally failed.
Question, my red donut is almost completely dead, can they replace the reticle while they are at it? I want the green donut or green horseshoe. Are they going to charge me an arm and a leg for reticle upgrade or can it all be covered under warranty? If not, have them fix it and just use it as is? You can get a functional TA11 for between 600-700.

| To recharge the tritium is going to be a bit of a pricey proposition. I'll let people who had it done chime in, but expect to pay in the hundred dollar range for new tritium to be put in. Not sure on the reticle, but fairly sure they would charge you for that too. How much is a good question, but I'd also expect it to be in the three-digit range. All said and done, I wouldn't be surprised that the final tag would be 50% of the retail cost of the sight to put a new reticle in and recharge the tritium. |

I wonder if they have to take it apart to fix the seals, wouldn't it be any easier to swap the reticle as well?
I am at crossroads. Because I am trying to see which way to go and what is cost-efficient. I need a 308 BDC ACOG with crosshairs or horseshoe, or perhaps something with a little more power, to swap between a 16" upper with 77gr SMKs and a 7.62 MBR. I've never had that much luck with the donut at 300m, I already have another TA11J-308 and liked it a lot more for the increased precision. If all they can do is fix the condensation under warranty, maybe then it makes sense to sell it as is after the repair. Not sure it makes sense to pour 500 bucks in it to fix the reticle. Some solid data would be appreciated here. I am sure over the decade optics have vastly improved as well, internal coatings for example. |

Your best bet would be to call Trijicon tomorrow; they'll be able to give you a good estimate. Some people report the recharge rate was very reasonable, some will report it was insanely priced. It just depends on what they say, I suppose. After 12 years, that optic has definitely given you a lot of service.

I will do that and then decide which way to go. Fix this TA11C, or get TA11J-G308 or maybe even TR20-2. Just a heads up with the TR20-2.........I had a TR20-2G, and I just didn't like it, and here's why- (all are my opinions, and not fact) 1. Adjustments are in MOA, yet the reticle is in MILS (if you get the Mil-Dot reticle), which makes doing any doping a pain in the ass. 2. Scope is 2nd Focal Plane, which means you have to zero it at 9x for the Mil-Dot reticle to be accurate. Also be aware your POA/POI is going to be different at any magnification other than the 9x you zero it on. 3. Optical clarity isn't as good as an ACOG. I recently sold the TR20-2G, and bought another TA31ECOS ACOG. I love the Dark Earth Brown anodizing, and the fact that it has a 4 MOA RMR, and Iron Sights built in, along with a decent A.R.M.S. mount (although I just ordered a LaRue LT-100 for each of my TA31ECOS's) makes it, in my opinion, the best bang for your buck if you want an ACOG, but want up-close capabilities. If your gonna replace your TA11, check with these guys- 4SCOPES They don't sell display models, and their prices are insanely good, with free shipping. I got all my ACOGs from them. 
ETA: TA11J-G308- $1128 shipped at 4SCOPES |

Does all this apply to TR22 also?
Thanks for the link. I am committed to the TA11 platform, more or less, due to the generous ER, you need that with 7.62. I just decided I like green a lot more than red. Tried crosshairs and while accuracy improved, a donut/horseshoe is easier to process. |

I can tell you that the AccuPoint is made in Japan, and assembled in the U.S. at Trijicon. The glass in the AccuPoint, if I remember correctly, is Japanese, which may account for the difference in clarity between the ACOG and the AccuPoint. |

While glass in ACOG is OK, in my view, it's just OK and does not generate a "wow" factor like S&B or Swarovski and other "Alpha" optics. This may be however due to the objective size. I looked at a Swarovski with the 42mm objective and it's stunning in every way. Field of view, depth of view, clarity, brightness.
TA11* is however very compact (IMO) and seems more durable, all in all. Doesn't have a circuit board like all these flashdot models. I am going to call Trijicon tomorrow for their guidance in this matter, and also try to dry out the TA11C on the car's dashboard. I wonder if the seals went bad due to age. |

FWIW, talked to Trijicon, they say to replace the burned out red donut reticle, it would run $542 each, clearly not a cost-effective solution.
The condensation issue could be resolved for free under warranty, but it only solves half of the problem, because tritium is a big part of the ACOG appeal. The red donuts weren't all that bright to begin with. I have an ACOG with green reticle, it appears to be much brighter than the red donut, even when it was new. I am not going to upgrade either one, and consider either an Eotech or more likely a compact ACOG like TA44. |
| I would definitely call first. They will ask for the serial #. They will likely tell you that it is all clear for repair. Some people are told that it is a stolen military optic and if you send it in they will NOT give it back. If they give you the OK to send it in for repair then I would have it repaired. I personally value an ACOG even if the tritium is dead because 99.9% of the time you use it with ambient light to illuminate the reticle. |
|
Not 99.9%, but more like 50% since it is dark outside half the time.
I have trade pending for a green horseshoe reticle. It seems both more precise and easier to see without ambient light. I tried a TA11J-G and it is the most precise ACOG, with a reticle that glows like a neon sign. Or green donut. When buying an ACOG, figure in tritium upgrade price down the road. I think it is the best there is, but expensive. With the dead tritium, it is nothing more than a mediocre optic you can buy all day for half the price. |
