I have a blue heavy barreled MKII in a factory plastic stock which I have had for over five years or so and my brother in law just won a stainless heavy barreled MKII in a wood stock. I have had scope mounting problems

with both of these rifles. When using rings that are not adjustable I have have noticed when using a bore sighter with a grid in it you can see how far off a centered scope reticle is. My brother in laws scope can only

go 4 clicks to the left of the center of the bore scope and has more than enough clicks the other way. I had to
make special adjustments to use my scope.

My scope was a Nightforce and his was a Swift. I know there a lot of people who mount a scope and go down the the range and sight there rifle in and as long as it hits the bullseye they are satisfied but they

don't know they may be only a few clicks away from running out of adjustment. A gridded bore sighter will show you how your scope matches up with the bore.
