And with some red dots, you can still use your BUIS while looking through the dead optic, so it wouldn't have to be removed necessarily.
Also, it will develop your shooting skills much faster to start out learning to shoot with irons than with an optic. I did the optic thing first and wished I had done irons.
However, because you have a railed front gas block, you CAN NOT use MagPul BUPS (back up polymer sights) or they will melt. So you'll need to get a metal front iron sight if you want to have them. Just a heads up. My rifle was the same way, and I ended up installing a low profile gas block and a 10" free float rail so I could get a longer sight radius and use whatever I wanted.
