Thread: Zero MOA rail/base - why?

Take a tikka rail for exemple:
At 0 Moa: top and bottom are parallel, and the screw holes and screw head recess are straight and 90 degrees to those parallel surfaces.

At 20 Moa ( or any other angle): your screw holes and head recess are drilled at 90 degrees to the bottom of the base , but all your picatinny slots are milled on a different plan parallel to the angle of the top surface. Which can involve a few more operations depending on what cnc set up is run.

Just that makes the price go up, or the manufacturer does not want to bother and just make and sale 0 Moa rails only and that is it.

But the majority of rails on the market are the same price for 0 MOA and 20 MOA.

It is cheaper if there is no rail and only built in dovetail or 2x weaver base.
