Mine came with a folded cardboard backer/label within the plastic clamshell packaging. An instruction sheet was folded up inside the cardboard backer/label.
For both front and rear ringmounts, parts (C) wedgelike locking piece, and (D) mounting screw, are mounted on the right side of the rifle.
The rear ringmount should be pushed forward so the recoil stop pin is in firm contact.
The front ringmount should be approximately in the middle of the front mounting rail. Notice that each move of 1 mm forward alters the point of impact about 25-30 mm to the right at a range of 100 m. Move backwards alters the point of impact to the left. Front ringmount should be moved if the windage adjustment of the scope is not enough.
Hope this helps.
