* ???Wish I spotted this before I spent six hours trying to adapt the commercial "sporter" screw to the new Beaver Barf set; this had zero metal components with it, and the stock screw from the "Sporter" is over 1" too short for the Beaver butt stock.
The Woodworking Shop precisely sliced off the forward 1" from the stock, in order for the Sporter screw ( with 2 or 3? thin, luckily very narrow washers: Loews's) to go into the receiver's screw hole (Nobody else I found seemed to advertise an original screw). Careful measuring worked out well. What a pain..............
