Yes Heli-Coil will repair your damage thread in your rapid...
But if you have access to a machine shop.
There is a better solution!
I have been using Time-serts for sometime now, in aluminum!
They are full steel inserts.. no more galled threads!!

Here is one I used in the 10-22 Takedown receiver I Machined.

Good Luck,

Before you do any drilling for an insert just check the depth of the stripped thread.

The block on one of mine is stripped for the first 1/4" but there's almost 1/2" of good thread under that so I just use a longer bolt  ;)
Start with the bolt in the stock as far as it goes in & measure how much thread protrudes through on the inside, (measurement A)
Now measure the depth of the hole, (B).

Subtract A from B and what's left (C) should be good usable thread for a longer bolt.
Then add C on to the length of your existing bolt & that's the length of the new bolt you want,
use a washer on the bolt when you fit it to give a bit of clearance at the bottom of the hole.

It's a good idea to just chase out the thread, make sure it's clean & dome head hex bolts in 1/4"unf are cheap on the bay

A better idea might be to fit a stud and chemical lock it if there is any thread left. In my crimes against Rapid block box I have one that has been drilled out and breeched the reg chamber.

All sorted now
Got it helicoiled good as new
And better in my opinion
Why didn't theoben do it or the metal inserts
