hey fellas just a question about scope mounts for my Norinco M-305 (M-14 clone) i got a mount from the dealer and mounted it acording to the info but the sucker has developed a wandering zero, :evil: I sight it in lay the gun down, walk away to check the target, come back load another magazine fire a round down range and it's off 10 inches. :evil: from what i can tell the big thumb screw isn't staying in place so i gave it a good twist with a wrench :twisted: ( and no i didn't strip the threads) and it seemed to stay put but i just got back from guiding today and the gun hasn't left the safe in two weeks but guess what, the screw was loose. if this keeps up I'll end up witha screw loose :twisted: . So if anyone has a solution drop me a line I'll be around 'til the 1st of november.
