AR Castle Nut Wrench & Law Folder Install

[treillw]

Installing a law folder on my AR.

Looking for a cheap AR castle nut wrench. Lots of them show up on amazon, but I'm not sure which will work. Recommendations?

My castle nut is staked. Is it a good idea to replace the metal piece that is deformed into the nut? What is the metal piece called? Good place to buy one?

Also, curious what happens if you fire the gun with the stock folded. I see that it says do not fire with it open. Just curious, not planning on it.

Thanks!

You'll have to restake castle nut and you can just wrench the stakes free on the oem castle nut.
