I love the idea of your Field Survival Tool. There is only one reason I have not bought one yet.

I have an Adams Arms Piston kit on my Rifle.

I am surprised that. With your relationship with Adams Arms, you have not made a tool for their system (maybe with a scraper for the piston cup).

And make it to fit in a Magpul grip , please?

How about a customizable one? Just sell the scraper to replace the gas tube cleaner on the standard tool?
