The KNS Precision AR-15/M16 Gen 2 MOD 2 Non-Rotate Trigger/Hammer Pins should work fine with that trigger.
Yes, but I wouldn't suggest them! I would only use ELFMAN because they are cut for those boxes and anything else like springs or a link. Just use NRsear bar and tab from them. Remember,,always be smaller in pin size then hole. That way they'll be loose. Always buff out some with your choice to be smoother then baby butt. That way if you aren't a C3 you'll be legally smoother then any C3 out there if done right.
