TTT new guns [HELP]

Ok so i am trying to add some new weapons into my ttt server that you cn randomly pick up off the floor but for some reason it doesn’t seem to work, Most probs because i ain’t doing it right but i was wondering if someone is able to help me out?

These are the ones i am trying to get:


What doesn’t work? Are they appearing on the floor at all or can you not just pick them up?

They (from the look of it at least) will only spawn on maps that have random spawn points on them. They wont spawn in place of m16s or anything though.

Ok i have managed to get one get to spawn on the floor, can pick it up and everything… How can i replace the m16 with another gun so the new gun will always spawn where the m16 spawn?
