I've ordered a Howa 1500 that hopefully will be in town at my FFL in a week. I need to know what kind of bases and rings to get for it. I plan to possibly put a Nikon Monarch 4-16x42mm scope on it... if this makes a difference as to how low or high I might need to be mounting the scope, or if it would affect the size of rings needed. Do you prefer a one piece base, and if so, why? I've never mounted a scope, so thanks for your help.
