That's an understatement...
First, take out your bolt catch assembly (catch, detent and spring). Replace it with a simple Armalite or a Phase5 EBRv2.
Second, pull the entire trigger group out. Replace it with a Geissele, ALG or a CMC.
Third, pull the fire control and replace it with a BAD Inc, AXTS or similar ambi set-up.
.... do you see where I'm going with this???
Take down and pivot pins are next. Don't forget their respective detents and springs. DPMS parts will suffice here.
The magazine catch should be next. The Armalite AR10A will fit. It's beefier than the LR308 version (which is just an AR15 part). Might as well get a Norgon or Troy left side release while you're at it.
I'm pretty sure I've "cleansed" your rifle at this point.
