The buttplate inlet has been cut close to the buttplate shape, but a small amount of inletting will be required. Buttplates have been straightened to match the wood shape, though some small amount of further straightening may be helpful; in that case a vise and adjustable wrench can be used.
It is a good idea to lightly file the buttplate edges that mate with the wood to provide a clean surface for inletting. When fitting the buttplate to the stock, use transfer color and carefully remove contact points with a chisel or file until a relatively close fit is achieved.
Secure the buttplate by installing the included screws. After the buttplate is screwed in place, the fit can be adjusted by using a hammer to peen the soft brass against the wood, which allows small gaps to be closed.
Tip: The pilot hole in the wood for the top buttplate screw is offset forward on the stock. This is intentional; it helps pull the buttplate forward as the screw is tightened.
