Client gave me one. I keep it for my contingency triad.
Recs: I'd dump the bcg. Mine was AR cut, not M16. I put a Centurion Arms mil-spec/TDP bcg (Carpenter 158) in it. (Bought several bcgs from Monty as back ups. Yo, Freeman, I heard you like backups so I got you a backup for your back up)
Accessories: I put Troy battle sights, an ALG ACT trigger on it, Radian CH, Magpul grip, and Magpul rail protectors on it.
