I have an Aimpoint Comp M3 with the Aimpoint 3X magnifier on a Larue pivot mount on my M4 Carbine.
To me, this seems superior to a setup with the ACOG. The magnifier is out of the way the dynamic short range stuff. Then, if you have a target ID problem or difficulty getting a sight picture, flip in the 3X magnifier. It is very fast.
Close range:
I know the ACOG can be used with the BAC up close. But, I think most people would agree the Aimpoint is better. I consider close range threats a bigger priority due to the speed and dynamic nature. It takes less skill from the bad guy to hit you. It is harder to find cover against a closer threat.
Long range:
They have similar magnification for target ID or getting a sight picture for things that blend in. The glass and light gathering is good on both. The only difference is the bullet drop compensator. However, my experience is that most people are very poor judges of distance, especially under stress. So, I am not completely convinced of the magnitude of the advantage.
Summary
You give up a little long range performance with the Aimpoint/3X combo. However, you have superior short range performance with the ability to set your gun in 1X red dot mode. Given that close range threats are more deadly, I don’t see why the magnifier approach is not more popular.
Can someone enlighten me?
