Another thing to consider is if you run rifle matches. This case I would argue an ACOG is better than Aimpoints or EOTechs with the flip to side maginifier. Some ACOGs, equiped with BAC, give you the ability to keep both eyes opened for target aquisition, the problem I've seen is that you still have to get closer for a proper aim. This however is an advantage if you are running matches as it is faster than flipping the magnification to the side and back depending the distance you are shooting.
I'm not sure I've ever understood the whole concept of the BAC ACOGs. I fully understand BAC, and use it myself, but I don't understand what difference there is between the standard ACOG and the BAC model, short of possibly a brighter reticle. The EOTech supports two-eye open targeting in the absolute truest sense. Rather one eye is looking through the glass and the other is just open, or rather both eyes are looking through the glass, the results are still always the same (without magnification), that being an absolutely 100% crisp and clear sight picture along with a 100% crisp and clear reticle. In fact, in my opinion the holographic nature of the EOTech makes it one-up the Aimpoint in this respect as well. Because of the holographic design, it's not a reticle or dot that is seen on a close object super-imposed over the target. Instead the reticle becomes a part of the target. Your focus is 100% on the target and yet the reticle is 100% in focus as well, not even a small or slight bit of blur. Sorry, I'm rambling... Back on point...
The point is, with the magnifier engaged the EOTech works perfectly fine with BAC technique. And again if the only difference between the ACOGs with BAC and without is the brightness of the reticle (and from what I can tell, that's it), the EOTech can be adjusted to everything from "barely make it out at night" to "it's in full bloom in the brightest of sunlight and I can't see a @@@@ bit of the target..." LOL...
At the end of the day, for anyone considering optics for their rifle, I think this discussion makes one thing very clear. It's not one size fits all. There is no "best" sight. It's all about your personal preferences and what makes you most comfortable. I've seen lots of posts on other forums asking about what sight they should put on their rifle... I think I have a new answer for that question...
NONE...
That's right... Don't spend one @@@@ bit of money on anything until you can arrange to try rifles with the various sights on them... Try one with an ACOG, try one with an Aimpoint, try one with an EOTech, and try one with a more traditional scope. Engage close targets, distance targets, and various drills. If you decide to go with a traditional scope, even then you owe it to yourself to try at MINIMUM a cheaper Bushnell and a more expensive Leopold or similar. See the differences first hand and ONLY then should you make a choice...
Yeah, your right... That's all a bunch of BS and completely impractical... Which is exactly why the next point is so very important...
Aimpoint, ACOG, EOTech... It doesn't flippin matter... You buy either one of those and you WILL be happy. You'll love it like it's your first born. That doesn't mean one day you won't try something different and WISH you had made a different choice, but you'll still walk away happy with your own...
