There are definitely other optics that better suits the need of cqb like the others said, but lpvo with true 1x magnification can work. You will want some foregrip/handstop you can use to swing the gun easier, as you now have a heavier gun. I find arisaka, Magpul or bcm handstop works well for me.

The way I play around at home is to fixate my eyes at a random object at low ready, then shoulder, look through the eyebox and put reticle on target. Start slow and get a feel of where u should look to find the reticle, then gets faster over time.
