Restrictions

Hey me again haha

So this time I was wondering if there is something out there that could allow me to restrict certain things on my server such as weapons or entites without going into the file them self and changing them to admin only. I have seen something called urestrict but i think it is years out of date. Any ideas?

Also I am using ULX for my server admin tool thing.

Thanks for any replys!
