Was thinking about mounting a Primary Arms CQB ACSS 2.5X on my RDB. I shoot my ARs primarily 25 yards. My reasoning: the rifles I own are for defensive use. Also I shoot at local indoor ranges where the lanes are 25 yards max. As I looked more into it the CQB and it’s philosophy of use it seems that, for my needs, it may be a little more than I need. Am I mistaken?
