| I am interested in getting a ACOG and from what I have read here there seems to be a few different models is that correct and which is better and where or what site has comparisons? I will be mounting it on a M16 11.5 in and also would like to put on a Shrike upper I have coming. Thanks for any info. |
| You will want a BAC model that is the TA11, TA31 or any of the Compact models in 1.5, 2 and 3x magnification. Go to [url]http://www.trijicon-inc.com/[/url] and read up on the specs of those models. The BAC allows you to have a dot type sight for close in work or use the magnification of the optic for longer shots. |
| There are litterally many dozens of models. Do an initial review are the trijicon www site, see whats available and narrow your choices down to those that interest you. Then come on back here and ask questions and we'll get help you get the one that will best suit your needs. |

I'm doing the same thing and I just e-mailed (2 days ago) the Trijicon people about wether or not I could get a TA-01 NSN ? They haven't replied [b] that is the big issue to me I could buy any sight but what matters is the BDC without it it's just an expensive piece of shit. There's very little difference between the M-4 and 11.5in barrel (like 3 inches and 170fps velocity) < and 170fps equalls approximately a 50 yd M-4 velocity so I'm guessing the reticle should be damn close. If you get the NSN sight you can buy an optima mount that replaces the rear ACOG back-up iron sight from SPECWARGEAR.COM and that will give you better results than this BS bindon aiming concept (which is just fancy for close but no cigar- and limits field of view by about 30% due to one eye being blocked by a sight.[/b] And before you bring out the hanging party- remember how they say BAC works for close range (like 50yds?) it's because it isn't very precise. < the Optima should give you pinpoint 0-225/250meter shot placement and the ACOG can take care of the rest. |
| I was searching the Equipent Exchange for a different optic a friend of mine wants to pick up and I have seen SEVERAL ACOGs for sale there. At good prices too. I specificly remember seeing a few TAO1NSNs for sale. Just because vendors dont have them doesnt mean you cant get one. Keep your eyes peeled and I bet you have one at a good price soon. |

If you get the NSN sight you can buy an optima mount that replaces the rear ACOG back-up iron sight from SPECWARGEAR.COM and that will give you better results than this BS bindon aiming concept (which is just fancy for close but no cigar- and limits field of view by about 30% due to one eye being blocked by a sight. Well, everybody experiences BAC differently; but my own experience has been that I have full peripheal vision. The only loss in field of view is when I am looking at the zoomed view with BAC, the magnification creates a small crescent of blocked view on both sides. Even then I wouldn't say it is anything like 30%, more like 5%. And before you bring out the hanging party- remember how they say BAC works for close range (like 50yds?) it's because it isn't very precise. BAC is as precise as the shooter is. It is more difficult with some reticles than others; but hitting a target with a BAC ACOG is no more difficult than hitting a target with a non-BAC ACOG. The TA01NSN will be more precise because it has a crosshair reticle; but that has nothing to do with BAC. For a comparison, I think the Optima comes in 3.5 MOA dot and 7 MOA dot. I'll leave it to you to decide whether you will be more precise with those dots or any of the ACOG reticles; but I think most people would have the best luck with the ACOG reticles. I guess it all depends on how we define precise. new_arguy did MOA or better out to 400 with the donut (not the most precise of reticles either). Is that precise enough? |

[rolleyes] Green, c'mon... as far as I can see, you are missing the point. BAC is as accurate as the shooter, that is true. But the BAC really is not supposed to be used for precision shooting. Neither is the Optima you are suggesting. Both are made to help the shooter put fast shots on relatively close range targets as quickly as possible. Put it this way. If you have the time to place that dot reticle of the Optima presicely where you want it and make the most accurate shot you can with it, then I think that you have time to use the magnified image of either that ACOG, or the BAC equipped ACOG. In which case you should be skipping the optima all together. Because the magnified image is going to help you achieve better accuracy. Topping the NSN model with a Optima is not to make it a more accurate scope. It is to make it a quicker scope. It is no quicker than the BAC ACOGs. However, BAC ACOGs are FAR(x2) more sturdy than the Optima equipped NSN optics. That fragile thing sitting on top of there will be the first thing to go. And when it does, BAC AGOCs will still be as quick. I am not saying putting the Optima on top of the NSN is necessarily a bad idea. I dont think it is a bad idea and in fact I want one for mine. However, it does nothing better than the BAC ACOGs and it is weaker. Last thing... I have consistently achieve sub-mao accuracy using the donut reticle of the TA31 at 300 yards... not 400. 300 yards is the furthest I have been able to shoot for groups. However, I was able to hit the center square (maybe 1' x 1'?) of the giant steel gongs at the 450 yard range during BRC. In fact, I was able to hit the 450 gong (maybe 5' x 5' all in all) from [b]offhand[/b] using the TA31. I could hardly believe it myself. It was my first time shooting at those distances. There were many witnesses to this and we were all pretty impressed. ACOGs are great! |

The only advantage to the Optima/Dr Optic sight is the lack of phoria when in unmagnified mode compared to BAC. What you give up is a constant cheek weld and speed since you have to take the time to move from one optic to another. BAC is supposed to be for placing center mass shots on moderatly sized targets under 100m. As new-arguy stated if you have the time to be precise with the Optima you have the time to be using the regular scope feature. The reliability of that little sight comes into play also. Go check the prices of a waterproofed/milspec Dr Optic and you will find that, if you try to make the Dr Optic as tough as the ACOG, the BAC looks like a much better scope overall for a lot less money . If you use the Optima then you have a fragile and not waterproofed sight that can fail on you. Either way the BAC ACOGS are better from a cost/benifit perspective. |
