"Ultimate" AR-15 butt-stock repair/cleaning kit?

[PanhandleGlocker]

Hey guys, not sure if something like this has been posted before and not sure if this is the place to post it, but,

I'm thinking of ideas to make a kit that holds repair parts and cleaning equipment all in the butt-stock of an AR-15, A2 style of course. But cant think of some sort of container or bag that will hold it all whilst still fitting into the butt-stock.

Also what else would I need besides replacement springs and bolt parts?

Thanks guys! Cheers!

Sight tool?
If you have lights or red dots, possibly batteries?

Cigar case? Variety of sizes, metal ones have thinner walls than plastic. Example:

I have a MIAD grip insert that will hold a spare bolt and firing pin. It's easy to swap out a bolt or bent pin in the field. It's not as easy to swap out just an extractor. And I carry a Leatherman MUT as a do-it-all tool for the AR. I've never needed anything else but the above items to keep my AR running.

here you go. Check out any mil surplus store or seller online.
Add or remove stuff as needed to make it fit.

There are also multi tools made just for the AR that fit in the pistol grip.
