POI shift

A heavy can on a thin barrel can have more shift than a heavy can on a heavier taper barrel or light can on a heavy barrel. It is not so much the shift but is the shift repeatable when you take it off and put it back on. The repeatability depends on the mounting method and how well the mount is made along with the quality of the threading of the barrel. Direct threaded cans should be more repeatable than quick attach, but there are some quick attach that are pretty good as well.
