Can someone please give me an explanation as to what BAC is on an ACOG and how it is used? Thanks, |
| Banden(spelling) Aiming concept. It uses a fiber optic tube that uses the light surrounding you to illuminate the reticle, it also feature trilium insert for night work. the reticle comes in triangle(TA31a) donut(TA31), or the Chervon(TA31F). more options avail for the TA11 models. The reticle in fast moving engagement will act sort of liek the OEG of the past and give you the red dot effect, but once settle in on the reticle with a good cheek weld, the 4x comes into effect. I personally have the Triangle reticle and it works well for me, I was going for the donut, but can't stans the 15 weeks wait for it to be in stock. settel for the triangle and loving it. BAC equipped ACOG are the best CQB to 300m sight on the market. |

With a little practice, any magnified optic can be used in the manner associated with the BAC ACOGs. It's all about using both eyes while moving to your target. Since your brain wants to "see" the clearest picture possible, your off eye will dominate while you are moving, and your brain chooses the unmagnified image. As soon as you stop moving, your brain will auto-select the magnified image from your dominant eye (behind the scope), and voila`, you have experienced the Bindon Aiming concept. The beauty of the Trijicon system is how they use their combination of illumination methods to provide a more or less constant "optimum" level of reticle illumination. I say optimum because when you are seeing the off eye image your brain has to also superimpose the reticle, which is only seen by the dominant eye. The easier the reticle is to pick up, the easier it is for your brain to get it right. A good exercise to train yourself to do this is to look through any scope, keep both eyes open, and the optic stationary. Focus hard on a target and you will see it magnified (through the scope). Now try to force your vision to include the picture from your off eye. As you concentrate on that input you should see the non-magnified view superimposed over the view coming through the scope. You may have to close your dominant eye a few times to get this started, but with practice you will easily be able to see both sized images together. When you can do easily this with a standard scope, an ACOG with BAC will be a snap to use. Just see your target with your peripheral vision and start moving. You will see the target as the retical comes to it in you unmagnified vision and as soon as you start to settle on the target you will switch to magnified view, still on target. Eventually you will engage and move on without ever getting to magnified view. Ready for CQB. Paul mstn.biz |
