Dont think i can use this for a .308 716 sig can I?

I tried zeroing my ruger american in 308 and its definitely not stable enough

Is this item sufficient for use with a bolt action .243

Of course, that's what is made for. I use it on both of my Savage bolts, 6.5 and 243. Holds your rifle WAAAY steadier than you can. Makes sighting in a new scope easy peasy.

Can you hold and zero an ar-15 and ak c39v2 moe, both with noncollapsible/pinned stocks?

Yeah this will work great for that!

Will it work with an Ruger AR 556?

It should work and the center pad removes to allow for the magazine. But to be honest I would look at the Caldwell Stinger rest.
