The heli-coil kits come with the coils, coil installer & tap for the coils to thread into.
You will drill the hole out bigger that the M4 so the tap can cut new threads into the body.
Give me a few minutes & Ill see if I can dig up a kit online.

I hvent ordered anything like this from mcmaster so you may end up having to buy each tool & a pack of inserts. The kits we have at work have like 10 coils, tap & installer.
