Thanks to the abundance of good data from folks on this board, I'm slowly working my way toward the best ACOG for my 20" flat top. I'll be using M193 exclusively as I have enough of it on hand to last well past when the actuarial tables tell me I will have assumed room temperature and will no longer have use for the rifle. Question: Does this BAC stuff really work? The ACOG brochure claims that when the scope is in motion in the verticle or horizontal planes, the magnification appears to go to 1X (thus greatly enhancing the speed of close-in target acquisition), and reverts to its nominal magnification when scope comes to a stop. This sounds to me like some kind of unatural shit, probably punishable by God. But then, the way the Aimpoints and Eotechs work, with their no-parallax, strikes me as black voodoo. Nevertheless, work they do. I would much appreciate any input from actual users of the BAC models. I would also appreciate any input from actual users on whether or not that light-gathering thingy on top really matters under actual conditions. Thanks to all. SD |

Hello Me again, I too was skepticle about the BAC. I have a 3x20 mini ACOG and find that the scope performs as advertised. How this works I really find it hard to explain. I can tell you that not everyone gets it at first. Some of my shooting pals struggled with the BAC. There are many threads written on this subject which outline the science behind BAC. You might want to make liberal use of the search function. Happy hunting, Gary |

It does work; but one thing you should be aware of is that the dot shifts as you zoom into the magnified view. For example, looking at it in "unzoomed" view, the reticle will appear right over the target; but as it zooms, the reticle jumps to the left a bit because I am now looking at the target through my dominant eye and a different angle. You can compensate for it easily enough; but people who are not used to dealing with that may find it unsettling at first. |

Overall it's a neat thing, reminds me of an occluded-eye gunsight. |

[b]Last Defender:[/b] You say you have a mini ACOG 3X - 20 with BAC. Do you find this device really useful for close-in snap shots? The reason I ask is that I once had a US Optics 1-4X variable on a 16" gun that was so eye-relief and cheek-weld critical that it made me nuckin futz trying to get it on target at close range in a hurry. After attending a carbine course, I gave it a dignified burial by launching it over the wall into the wash out back with a slingshot and ran to the Eotech store. I appreciate the help of the members here more than my meager command of the king's English can express. SD |
| Bartholomew are you right handed right eye dominate? The reason I ask is I am right handed left eye dominate and told I can't use ACOG's because of this. Just wondering if anyone else out there has my problem and has tried them anyway. I want to purchase one so bad but want to be sure it will be of use to me before I drop the cash. |

Quoted: Bartholomew are you right handed right eye dominate? I am. The reason I ask is I am right handed left eye dominate and told I can't use ACOG's because of this.

It can cause problems for you. You can still use it like a normal scope by closing one eye. You MAY have trouble using BAC though. When I use my weak eye I have two problems: 1) Harder to find the "sweet spot" where I can see through scope clearly 2) Brain doesn't want to use the clearer zoomed view through scope. It wants to use the unzoomed view my dominant eye sees. With training I can overcome both of those issues; just by playing with it and practicing using my weak eye. Perhaps somebody else can read and chime in, but I've read past posts by people who were cross-dominant and they seem mixed. Some find the ACOG unsuitable and some find it OK for their use. My advice would be to try before you buy if possible; and if not, buy one that you know you can resell if you don't like it. |

SD, The eye relief on the 3x20 mini is very small. I have it on my BM Target 20 and do not use it for close in work. For that I have an Aimpoint Comp. I do not think you'd be happy with the mini even with the BAC for shoot and scout activities. I am old an need the magnification to hit what I'm aiming at. Regards, Gary |

I'm right handed left eye dominant. Obviously, the BAC feature works better if I hold the rifle left handed, but I played around with it for about an hour and it's no problem through the right eye for me. I imagine some people can't do it, but it's not impossible. |
