Cal, order one of these NULA three function safeties from Brownells. These will lock your bolt but will allow you to cycle the bolt while still on safe if you press it down.
Pretty slick. I have a rather rare LH version on my KS. Installed easily.

If you just want a regular 700 safety Brownells also sells a Rifle Basix safety kit.

I'm not one of the Chosin Few but no more remarkable group of Americans ever existed.
