Is the Docter site on the 31DOC really much of a benefit for room clearing stuff? What about repositioning your head, etc. Isn't the point of the BAC to allow for close up work as well as far off stuff, making the docter somewhat redundant... Anyone have one, please comment! Thanks! |
| Your post is kinda one of the questions I had. I dont own an ACOG yet but im considaring the TA31F for BAC reasons. However I tired what I thought was the BAC with my normal crosshair scope and I dont understand it? seems like your brain can make the close range background clear but then the triangle or cheveron reticule blurry at the same time. Thats what happened with my crosshairs anyway. So I'm unsure about the same thing and dont know which ACOG I want. what gives? hinking.gif |

I kind of treat the Docter sight on top as a backup sight. BAC allows rapid acquisition with aid of the ACOG's lit reticle. The idea is that you use one eye to look at the target, while your other eye looks through the scope but superimpose the unmagnified image over the magnified until you're ready to shoot, this takes practice. The BAC concept can be used with any scope, due to a brightly lit reticle, it's visible at all times, it's made easier than unlit reticles like that of the TA01 series. If you use it like an Aimpoint, the point of impact is different out to longer ranges. Because of the eye relief, it's not as fast to acquire as 1X optics. I shoot with both eyes open even with unlit, 10x optics, only because I find it tiring to close my left eye for a prolonged period  I tried Victor's ELCAN Specter, a 1x / 4x with both a red dot and TA01-like reticle. At 1x using only the red dot, it isn't as fast as a true 1x Aimpoint or EOTech, again because it takes more time to acquire the dot. As to the Docter being redundant, while others may disagree, I don't use it because I consider it a backup sight, redundancy is its purpose for being

I love my ACOG TA31DOC. But I differ from Duffy. If I'm in a CQB environment I switch to the DOC without reservation. Using a jaw weld is just as natural and repeatable for me as a cheek weld. Maybe it's a physical thing and I've just got a big head. But it works much better and faster for me than staying on the ACOG for targets that are 50 yards and in. First pic using ACOG, next two using the DOC. It doesn't look as solid, but for me it feels and works well.    Hope that helps, JWL |

I would consider using both if it's like the ELCAN Specter or S&B Short Dot, where the 1x function is a built-in, as designed feature. Far be it from me to suggest the TA31DOC's Docter sight should be used as backup only, it happens to do a good job as a CQB optic, even if its position (above the ACOG) isn't ideal. I figure it's an improvement and replacement over the TA01NSN's backup irons, the BUIS of the TA01NSN are backup sights, the Docter sight merely takes its place. I rather enjoy the economy of motions by way of using the ACOG for everything, there's no two optics and two ways to use the scope. |
