I'm looking at replacing the gas block on my ar. Nothing wrong with it it's just the standard a2 sight post and I want to get rid of it due to my eotech and get flip up sights instead for back ups. My question is, how do I know of the gas block is a quality one, and what makes it better quality than others? Thanks guys!
