I need to find an addon

A few months ago I had garry’s mod and I downloaded some addon, that was a stool. It spawned a usable turret that could be pressed with the use button and get it shooting. It had different models, sounds, it also had settings, such as firing speed, damage properties (armor pericing, ignition bullets and etc).
Can anyone help me find this?

One of my favourite tools.

Aaaaaand the fix:

Oh nvm… one of the comment says the update broke it. Might not be entirely true, just check it out for yourself.
