Shorten Xtra wood stock
A competent gunsmith can perform the work. The Xtra Wood is a film-type of finish applied to the surface of the wood. While very durable, Xtra Wood can chip when making a cross-cut with a saw, just as a lacquer or urethane finish will chip if appropriate care is not taken. It is suggested that a miter or table saw with an appropriate 60 to 80 tooth, 10 or 12 inch finishing crosscut blade be used. It is also beneficial to place a single wrap of non-stick masking tape in the area where the cut is being made.When removing the masking tape, pull it back over itself, as close to the surface of the stock as possible.
