Hello! New to the AR platform, and I was gifted my new red dot optic. I don’t want a scope for my AR just the dot. I have it mounted, but the front sight is right in the way 😔 I’ve read about others just cutting it off and shaping it with a dremel, but would really prefer to not go that route. Any suggestions on whether I should just: A.Buy a new upper to have both “stock” and “tacticool” interchangeable uppers or B.Remove front sight and gas block and install a “low profile” gas block? Thanks for your help!
