Alright is it the vertical or horizontal plane? If the vertical is off send it back immediately for realignment.
Horizontal? Get a piece of scotch tape, a loupe, a locking cable release, and a measuring tape. Set you camera up somewhere stable, best if it's on a sturdy tripod. It's easiest to check infinity focus first. With the camera back open and a lens on set the shutter to bulb and lock it open. Carefully place a strip of scotch tape across film gate leaving a bit extra at the ends to aid in removal. Aim lens at something stationary and far, a distant building or a tower, open the lens to full aperture. Check your your scotch tape with the loupe. Is it in focus? If not, is it going past infinity on the lens? Turn the lens back a bit if it is and recheck your viewfinder and rangefinder patch. If it not even getting focus to infinity? Then there is a problem with the lens. Do the test again with another lens. Do both lens hit infinity focus but the rangefinder patch is still off? Then it's the camera. For minimum focus measure outward from the film/focal plane mark on the camera. You can use the markings on the lens or with your lens manual that would indicate a more precise number. You can also measure from any of the distances in between.
Rangefinders have this problem often. Bessas had this happen early in their batches but this was supposedly solved with using a better loctite compound on the alignment screws which are located under the hot shoe. But they are good cameras. I am lucky enough to have saved up and got deals on both a bessa r which I love and a bessa r4a which I am still adjusting too with such a wide viewfinder.
