Thread: Zero MOA rail/base - why?

I think the 0moa is just "safe" and probably saves gun manufacturers a lot of headaches.

Picture this, a rifle comes standard with a 10moa rail. In this case its just a regular mans rifle, not a super high end precision setup. The sort of thing that someone is probably expected to throw a cheap scope on. The cheap scope has 30moa of adjustment total. Now in a perfect world, all would be well. Without the rail he should be in the middle of his adjustment range with 15MOA up and 15MOA down, and with the rail installed he should have gained another 10moa, giving him 25MOA of upwards elevation. Problem is that never happens. A lot of the time the guy would not be able to zero the scope as it just never works out quite as it should and there isnt enough wiggle room with the type of scopes people would be expected to mount on this lower end gun.
I think gun manufactuers tolerances would have to be much higher in order to safely offer an MOA mount standard, on guns that people probably wont be putting a long range scope onto. If the dude with the 30moa scope cant get it zeroed with the 10MOA standard mount - whose problem is it going to be? The gun manufacturers, because in theory it should work, but in practice to get it to work failsafe, with scopes and rings whose quality you cant control - the guns tolerances is the one that has to be very high otherwise itll all come back to them. IMO.
