well see I have a NC Star 3-9x scope on my AR-15 now and it has a red dot on top of it. And yes I know NC Star is not the best but the scope does hold zero well. However after putting much thought into the Chinese invasion soon to come lol I know for practical purposes I really need a CQB weapon. So hince the Eotech. I really like the 512 but my whole thing is how much will I use it? And I know if it protects me once it paid for itself multiple times but i like the circular reticle with the dot.
