Thread: Zero MOA rail/base - why?

I would always opt for a cant/tilt in a base unless it is on a short-range bush rifle. Otherwise, if the scope is mounted on a 0 MOA base, a greater portion of the scope’s usable range of elevation adjustment will be wasted. The most common reason to opt for a 10 or 20 MOA base is because of the limited range of elevation adjustment in the scope.

Since all/most shooters don’t dial adjustments under their zero distance, the goal is to make most of the adjustment range on a scope dial-up to shoot out at targets further away. Ideally, if the riflescope has 40 MOA of elevation adjustment, 40 MOA will be available to dial up. Mounting a scope to a 20 MOA base makes that attainable.
