So I got an m&p ar for a Christmas bonus (what an employer). I have no experience with a ar platform. So I took my scope of my long range 308 and slapped on it,cause I am excited about shooting it. It's a fairly high dollar scope for me $1500.00. I mounted it and the windage knob is about an inch in front of the rear of the ejection port. if I shoot it tomorrow is there any chance of the spent casing ejecting and possibly hitting my windage knob that is about 11/4 inch above the centerline of the ejection port?
