Anyone know a mod I could use?

So I've been working on a zombie apocalypse project in 1.20.1 and I've been on the search for gun mods that work with armor stands and look relatively realistic, and I do have a mods that enable armor stand arms as well as most of my other needs, but I just can't find any that work, and I've tried most of the popular ones but they just plain won't allow me to do anything.

So if someone knows any mods or has some more knowledge I'd like to hear it.
