What would I need to do to my m&p 15 sport 2 in order to fit the 300 blackout upper ? Also do I need to call cfo to inform them of the change or it doesn't matter ?

Will you be selling just the upper receivers stripped?
1-Nothing. Just change upper. Even your magazines will be fine. Just make sure you never shoot 300blk through your 223 upper or it'll go kabboom! You'll need a bcg though, or you'll need to switch the one in your S&W upper to your NEA upper.
2-No need to call cfo. The lower is the registered part.
12.5 or 7.5?, I'm thinking 12.5
Go 10" if you cant pick lol
Quickly before I do this , what would be the advantage of switching from 5.56 to 300 blk?
