| Is BAC really worth it for ACOG's? Reason for my question is that the TA01NSN does not have it and it looks like a good ACOG - it was created for the Special Forces and I'm considering that vs. BAC, which from what I've read may take a while to get used to. If it takes a while to get used to, what happens when you shoot other scoped firearms and then go back and forth? |

Many Units that can have dropped the NSN and gone with TA11 or TA31 based scopes. Not everything designed for "Special" are good designs. BAC is a very useful feature in ACOG's I have a TA01NSN and a TA31F (and I want another TA31F) Anyway I will wait for new-arguy to list all the reasons. He is much better at explaining it (and he still seems to have patience for it too) [url]http://www.ar15.com/forums/topic.html?b=3&f=18&t=143055&w=searchPop[/url] and [url]http://www.ar15.com/forums/topic.html?b=3&f=18&t=141009&w=searchPop[/url] -Kevin |

The BAC ACOGs are far superior to the TA01 NSN for everything but punching paper at 100 or 200 yds. Or Its better if you are shooting at very tiny things at 100 to 200 yards. At 300+ yards the TA01 NSN loses its advantage of greater precision. For combat use, carbine competitions, self defense etc. the BAC ACOG is much better up close where the TA01 NSN is almost useless. As far as it taking a while to get used to, that is only if you want to use the BAC function while not swinging the scope. That takes a bit of effort to not do but it has nothing to do with how you will use other scopes nor will switching back and forth be detrimental. When you use a BAC scope you will swing it to the target and the field of view in the dominant eye will be blurred except for the glowing reticle which will superimpose itself over the non magnified non dominant eyes view. At this point it looks just like a dot sight to your brain but when the rifle sets on target you will notice your brain will automatically want to use the zoomed in view once the blurring stops. You can train yourself to not use that view and keep yourself from getting tunnel vision but that takes some practice. After a while you can switch back and forth from zoomed to unzoomed at will. This will not harm your ability to use regular scopes in any way and may help you use a quasi BAC effect to help get your regular scopes on target faster. You will learn to use the crosshairs superimposed over the non dominant eye to get a regular scope "close" and then will see the target in the scopes view and make a small correction instead of trying to "hunt" around in the scopes view and find some landmark to help guide you to some distant target. I suggest you try before you buy because a small percentage of the population has eyes that don't allow the use of BAC and you want to be sure it works for you before you buy it or it will be no better than the TA01NSN without the BAC feature. Also check the eye relief. For some people (myself included) the TA31 has too short of eye relief and can be uncomfortable and the TA11 is easier to use and more comfortable. Always try before you buy. Any major gunshow will have all 3 scopes so you can check them out and compare. |
| I have often been known to say the BAC ACOGs take a little while to get used to. When I say that, I am talking about maybe 10 hours of good usage. Maybe lees for some. Maybe a little more for others. Some people pick it up right away. Whatever your decision, do not let the fact that you may have to sepnd a little time behind it to really get used to it be a factor. To be honest, no matter what new optic you use, you will probably be spending about as much time using it before you become at ease with it. |
| The tritium is always there, just not as powerful as daylight through the fiberoptic channel, so when there is less or no daylight, you'd see the tritium light at work. Also, the reticle is black when not lit by any source. Try this, use a piece of tape, cover up the fiberoptic rod, & voila, you've got black reticle. We do this sometime in our matches, just because black reticle shows up better against tan color targets. |

Stupid question: When the tritium dies in your ACOG, can it be easily replaced and how much? A theoretical question I guess, given the 12 yr. reported life. TIA, Cleophis Trijicon will replace the tritium in BAC ACOGs for about $250 right now if I recall past discussions of the subject correctly. I think the non-BAC models may be a little cheaper. The only price Trijicon lists on their website is recharging the OEG - which is $35. Also 12 years is the half-life of tritium, not the life of the reticle. In 12 years the non-BAC tritium only reticles (TA01 and TA01NSN) will be about half as bright as they are new. In 24 years they will be 1/4 as bright as they were new and so on... The BAC reticles include a fiber-optic tube that illuminates the reticle with ambient light in addition to tritium, so the effect of the tritium decay on those will be less apparent until it is dark enough that the illumination is relying solely on the tritium (in theory anyway, call me back in 12 years and I'll give you a better report). |

Quoted: Please be aware that in the white/amber/yellow TA01 and TA01NSN there is a period of dusk that the tritium will not be visible and the black reticle will not either. Fortunately no one ever attacks then right [%|] You would have to be a moron to attack the US Army at those times. It is when we hold stand-to. For fun, attack right after stand-to when everyone is eating, doing weapons maintenance, shaving, shitting and/or packing their rucks. I loved playing OPFOR |
