An air gun rest is used for BB-gun target practice and sight adjusting. They are wooden stands that have a spot for the barrel to rest in and a spot for the stock of the barrel to rest in. They help the gunner keep the gun still while they study the gun for its accuracy. These types of rests quickly can be constructed with a few woodworking tools. They are not highly complicated and can be built in less than a few hours.
Drill a 2-inch hole through the 8-inch boards. The centre of the hole should be 1 inch away from the end of the board and 1 ¾ inches away from the edges of the board.
Drill a 3-inch hole through the 4-inch board. The centre of the hole should be 1 ½ inches away from the end of the board and 1 ¾ inches away from the edges of the board.
Cut through the centre of the holes on both boards using your mitre saw. Keep the 8-inch edge perpendicular to the blade for the 8-inch board, and keep the 4-inch edge perpendicular to the blade for the 4-inch board. The centre of the holes that you drilled through are the centres that you are cutting through.
Lay the 38-inch board flat, and set the nondrilled end of the 8-inch board on top of the board. The hole should be parallel with the 38-inch edges of the board. The 4-inch-wide surface should be flush with the 6-inch end, and the edges of the board each should be 1-inch away from the 38-inch edges. Screw two screws through the bottom of the plywood to secure the board in this position.
Set the 4-inch board noncut end on the other end of the 38-inch board so it is aligned with the 8-inch board. The hole should be parallel with the 38-inch length of the board and one of its sides should be flush with the end of the 38-inch board. Drill two screws through the 38-inch board and into the 4-inch board to secure it in this position.
Rest your air gun barrel in the 2-inch hole in the 8-inch board. Rest the stock of your gun in the 3-inch hole.
