I've been reading the reviews for my next scope for my 223 SPS Tactical and it looks like it's gonna have to be the 3x9x40 mildot Leupold MK AR scope. I really dig the idea of the 223 calibrated scope, I'll start out w/ 55 gr bullets and work my way up to a heavier bullet. If I have to send the scope in for a new turret for a custom load so be it. But as for now that scope looks like it is the cats A$$.
