Hello, I purchased a 4-16x50 Vortex Viper PST scope. I'm going to mount it on my Savage model 10 308. Since I spent good money on this scope I want to keep it in tip top shape and preserve resale. Should I buy a ring with 4-6 screws per ring to spread the survice area? Or should I lap the rings or something? Or is there a certain brand of ring that I should get? Let me know your thoughts. Thanks.
