I want try to scope my Colt Ar with carry handle. It has the bull barrel. I have this mount fron brownell that fits into the hole in the handle. I haven’t mounted anything yet but thinking of trying out and older Burris 4 x 10 that sitting around. I’m just not sure if this set up will hold together long enough to site in and play out to 400 yds. What y’all think? Don’t tell my to buy a new anything. This is just putting together parts that I rarely use and would like pointers from those that have tried this
