Need help as an Admin

I’ve played on other servers and asked for an admin to help destroy a wall, and he/she has pulled out an M4 to destroy it. I was wondering how do I obtain this M4, as an admin/owner?

You have to download a plugin. The command is /instako

I’ll try to find the name…

It’s in Rust++ and magma.

The server I played used Essentials and they had it, I heard that you can’r get it on essentials
