Original Note:
While muzzle velocity varies slightly with barrel length, bullet weight, powder, etc., the maximum expected measurement of a .223 round fired from an AR-15 would be roughly 3200 feet per second from the barrel. https://rifleshooter.com/2015/12/223-remington-5-56mm-nato-barrel-length-and-velocity-26-inches-to-6-inches/ Velocity slows significantly once it has left the barrel. http://gundata.org/blog/post/223-ballistics-chart/
