Need some advise guy's. I have a Kimber police tactical .308 26" barrel with 20 moa scope base mounted. The scope is a vortex 6.5 to 24 X 50mm FFP using Burris tactical rings (six screws each) to secure and two large nut's on the side to secure to the 20moa rail. I have loc tighted the screws (blue) on the rings and really tightened down the screws and bolt mount to the point that I am afraid that they will break or something will break. My question is what else can I do to secure this scope/ring assembly to prevent movement. The impact at 700 yards is ugly after firing 20 rds or so. I have had suggestions to double stick tape in the rings, also get screws that are nylok type (plastic in the threads) but really would like to hear from the hide what to do. Thanks in advance, Manny
