I bet it does change the POI, but I've re-zeroed my scopes to compensate, for what it's worth maybe that helps some.. At the end of the day it's a cheap piece of plastic with a flimsy spring and there's no way it'd outshoot the Harris or a Versa (which is what i think you have), I'm sure of that. It doesn't have elevation change capabilities either but, much like the trusty sand-sock, it holds my shaky barrel in one spot long enough to squeez of a round and if I have to pick up and run away, it's light enough that I can bust off one or two aimed shots on the way out. The cool thing about this gun is that it can do so much. You'd never throw a plastic bipod on a long barrel, and a harris/versa on an AK or AR probably doesn't make too much sense either. It all depends on what you want to do with it, which is what makes it so fun to own - choices.
