So me and the wife went about a month ago and decided we both wanted Ar's and I found one I liked and so did she. Hers is a S&W 15-22 and mine is the DPMS. I have not shot it yet because of my vacation trip and being busy at work and the other firearms ive bought needed some sighting in. Well im hoping this weekend or next I will be able to take it out and run some rounds through it. The one thing im not 100% sure on is the rear flip up sight. I might replace it with a carry handle sight but not sure of how the plastic flip up will hold. Any body have a problem with the plastic sight or am I just worrying to much? Maby a metal one, whats your thoughts. Thanks.
