Yes. The two silver KNS pins will replace the two trigger/hammer pins. The KNS pin with the threaded end goes in the trigger and the one with the flats on the end goes in the hammer. Just install them the same why as the regular pins, then once everything is in you install the retainers on the outside.
A tip: Lay the trigger in the receiver like you are going to install it. Put the selector in - just hold it in place - and then install the trigger pin. Sometimes if you do the trigger pin before putting the selector in it doesn't fit. Also, use a punch from the left side to go through the trigger pin hole in the receiver, into the trigger, through the disconnecter and out the right side. Insert the KNS pin from the right side, pushing the punch out (the punch is a slave.) You will have to wiggle the disconnecter a little. This holds everything in place. Do the same with the hammer.
Thanks. I figured it out. I was able to install the selector with everything else installed by cocking back the hammer.
Now it's almost completely done, but I'm not sure if the safety selector is installed properly. (I have the pistol grip on and the pin and screw, but can't tight the pistol grip screw until I get an allen wrench big enough.)
I cannot change the selector from Fire to Safe and vice versa unless the hammer is cocked back. Is this normal?
Once the selector is on Fire and the hammer is back in its normal position, I cannot change the selector to safety. Cock the hammer again, and I can change it. Does this sound right?
