Okay, CETME is not the "Top of the Line" .308, but I have one I am kinda stuck with. Dern thing shoots to the right (even though I went the max amount available to align the sights). I took a string from the front sight enclosure and ran it to the butt stock. The rear sight (welded to the receiver and non-adjustable) is not in line. It seems to be about 1/8" to 1/4" to the right. Any suggestions on how to break the welds without ruining the receiver and rewelding it into the correct position?
