ar/m4 flip up sights
i just got a new ar 223 flat top. it came with no sights. i am looking for some flip up iron sights for it. i see a big selection of sights of all price ranges manufactured by names i don't recognize. they all flip up and down and are adjustable and the prices range from under $20 to more than $100 for each front and rear sight. the problem is i am internet shopping so i don't get to hold and examine each sight. can someone recommend a particular brand or sights? is there really a big difference between high and low priced sights? is there a feature i should look for, or avoid? i will be using them with a reflex sight and some of the flip sights appear to be taller than others. would height be a problem? oh, price while not a deal breaker is being considered. thanks.
ya only got 1 arm and ya carry 3 guns for Christs sake. Well I don't want to get killed for lack of shooting back.
