Just got everything mocked up last night on my rifle. 700 SPS Tactical .308, Seekins 20 MOA base and Seekins 30 mm rings in LOW flavor (recommended by SWFA). All this holding a SWFA 5-20x50. Mocked it up and with the BC caps I cant even get a piece of paper between scope and barrel. With caps off its PERFECT! Question is do I go with MED rings or trim the caps? Or both? Looked at Seekins sight and the difference is only .05" if I read that right. I wonder will SWFA take the lows back since they have already been on the gun and a scope set in them?? I know the lower the better. Discuss.
