I’m trying to install a JP EZ trigger in my Knights lower. I have the trigger in, pins set and now the safety selector will not move into the safe position. What am I doing wrong? Will this trigger even work in this lower? 
Doesn’t the EZ trigger kit include a safety that has a set screw to adjust it’s relationship with the tail of the trigger?
Yes. And after I jack-hammered the pins back out, I realized “my” ambi safety wouldn’t work with the JP trigger. Apparently, you have to use the supplied safety switch. :eek:
You can get your ambi to work but you will have to fit the trigger and safety to function properly.
When I do the JPs I always have to fit the safety too.
I really like the JPs and have had excellent results with them on everything from heavily used ARs to precision ARs.
