Up until this point, I have always had Ken Farrell bases and they are very beefy especially in the area between the screw head and the contact point of the bottom of the base. The Nightforce, however, has a very little amount of steel between the screw head and the bottom contact area. I am assuming this is adequate based on the huge following that Nightforce products have but I just want to hear testimonials that support that. This base will be going on a 7mm mag. BTW, this is a 20 moa base with standard size screws. Will it be rugged enough supporting tactical style rings and a Mark 4 6.5-20X50?
