Been trying to find the optimal rings to mount a NF 56mm objective scope. Assuming the objective OD is 2.558 and my NF 20 moa rail is .268 I calculate I will have .024 clearance using Farrell hi 1.035 rings. If I go with the x hi, clearance would be .200 more. Is .024 adequate or too little. I realize this is probably not enough for covers. Platform: Rem 700 with Broughton 7.9 contour bbl.
