Thanks for the reply. I had given up and was assembling the original trigger back on the rifle and noticed that there was an extra hole on the main trigger body (that a pin goes through to hold lock the safety in place). The issue I had when trying to put the accutrigger was that there wasn't anything holding the safety on place. So I decided to switch the main body of the accutrigger with the body of the non-accutrigger that had the second hole (remove the pin holding the trigger in the main body). Once I switched the actual triggers out, and put the accutrigger into the main body of the original trigger assembly, I was able to get the safety to function properly. So now I have a safe and functioning accutrigger on my brothers rifle.
