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.

No problem. Anymore questions just ask. There is enough folks around here that any question will get answered pretty fast. Also Welcome to KUSA/SOC.

goto mcmasters site & in the search box on the left just type in the part numbers.

thx again buddy! you made my day! haha

edit: do you know what the kit comes with?

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.
