If I use a 223 Lower for a dedicated 9mm Lower what besides the hammer do I need to replace? I guess the bolt hold open catch will have to be replaced with a 9mm unit while using a Colt 9mm mag and a Colt one piece mag well adapter? Thanks

Hahn Precision has a new dedicated mag block ( $ 200 ). With it , you might not have to change anything else .
