Remove the BAS and slide the FP assembly out. You will notice that there are a set of notched nuts and washers on either end of the spring. There are flats milled on the pin that act as antirotation for the spring nut locks. Wrap a rag around the spring on the primer end for protection. Use some pliers and lightly squese on the spring with the BAS end on a workbench, compress the spring without damaging it. Let the lock washer fall away from the nut...the nothched pieces need to be seperated, now rotate the nut clockwise a few rotations. Release the spring and reassemble the bolt. Measure protrusion. For exact amount of adjustment you can devide the number of threads into 1000 and you will have the thousandths per 360* rotation. Divide the number of notches in the nut into that number and you have the amount each notch moves the pin.(I used to know all of that but I am ugly and ugly people can't remember stuff like that.)
Test and repeat until you have approximately .050 to .062. (some may say the high end some the lower end of that dimension).
