Lowest no gunsmith scope mount?

[lngstrt]

I still bore site ... Set up the rifle in a V notch rig, pull the bolt, peek and squint down the bore looking for the neighbor's front garden hose spigot and bring the scope to that target ... about 50 yards off.

As good as a laser bore sighter.

I also have the adjustable rings. Brought the Weaker K3 right back over the bore while the B-square was slightly off to the right.
