Elfmansingke stage triggers are popular to drop in these. It does take any Ar15 trigger group with her right length pins 📌.  But as of now, I'm keeping it stock.  I have been eyeing the Hoffman Suoer Safety if you are familiar with those. Just haven't pulled tthe trigger on it (pun intended). 

 Awesome, wasn’t sure if it was the super safety or sloppy seconds or which ever of them are lol
