I'd loose the big, bulky, heavy and basically antiquated rear iron sight. I'd get a lighter LaRue version if you must have the mil-spec style knobs though. Or if your on a budget, get a Magpul MBUS. They're light and work well.
It looks like you want to use it as a SHTF, close quarters, HD, range fun gun? So a red dot optic would be a good investment also...just my 2 cents.
