| I noticed that TA01's do not have the light gathering optic on the top. Do these run off batteries alone? |

The TA01 use Tritium only and they only Illuminate in very low light environments. The TA01 is one off my favorite ACOGS. Mike @ CSGW www.csgunworks.com [email protected] Here’s some testimonials about CS GunWorks for AR15 Board What do YOU have to say about CS GunWorks |

The Tritium will very but it will be 10 to 15years. Here is a TA01NSN I do not care for the TA01NSN because of the yellow illumination.  Mike @ CSGW www.csgunworks.com [email protected] Here’s some testimonials about CS GunWorks for AR15 Board What do YOU have to say about CS GunWorks |
The first part of your statement is 100% correct. The second part is somewhat misleading. Whether you are looking through (using) the scope or not, it's still decaying every second of it's life. So, to be perfectly clear, it will be half as bright after 12.32 year whether it's used or kept in the original box that entire time. One thing people don't think about is sure, the total amount used in the optic may be half as bright, but how bright does it have to be to light up the crosshairs? There might be four times as much as is necessary in the optic so after 12.32 years, it's half as bright but you still have more than enough to illuminate the reticle fully. Also remember, it's a halflife. Don't assume that after another 12.32 years it will be fully decayed and black. It will be once again, half as bright or 1/4 as bright as it initially was. Therefore, if 4x as much was used as was needed, it could possibly seem just as bright. I have heard that there is a noticable difference after 10 years so which proves that an ACOG you buy now will eventually someday no longer self-illuminate. |
I think my point was fairly clear when I said "Simply put, you can expect the tritium lamp to be half as bright in 12 years." My other point was that the person wouldn't use the Tritium illumination feature much, so it won't matter much whether it's half as bright or not because the vast majority of the time, he's shooting in the daylight where the Tritium lamp is useless. |
I have had an ACOG for 2-3 years, And Comparing it to the Day I got it, The brightness has decreased enough that there already is a Noticeable Difference. Nathan |

I surely didn't mean to argue with you. I just wanted to make the point about not using it not having anything to do with it "wearing out." I didn't know how much he knew about the tritium- which is not much being that he didn't know it was in there. I understand your point- that you probably won't use the scope much when you'd really need the tritium and that it wouldn't matter if it's lost half of it's brightness. I had bought a used TA01 and it was I believe 7 years old. I hadn't seen a new one before but the tritium was bright enough for me in total darkness and the possibility that I'd actually need it in total darkness was next to nil. Sorry if I came off as argumentative. |
No problem. I was a little more confrontentional than I meant to be. |
