First, have got a drill press? you can use a hand drill but it's nerve wracking. Look around the hood until you find one of those little flags that the lawn spraying companys use to warn you to stay off the lawn, sneak back late at night and get it. Or you can by one at the local farm supply store. If I remenber right they are just a bit over 1/16 inch in diameter so a 5/64th inch bit will work. Center the bit in the open end of the probe and drill in about 3/16. Cut the probe off just behind the hole and smooth the out side with sand paper. Stick the wire in the hole until it bottoms out and then measure from the shoulder of the bolt out 1 and 3/8 inch, mark and cut off, pull the wire out and mix a 2 part epoxey glue up and glue it in place. After you reassemble the receiver, bolt and barrel tweek it probe up/down side to side until it pushes a pellet smoothly into the barrel. Good to go.
