Why to add anything to mod I posted? It's already there and it works. What you posted is not generic .tik file BTW, original Multiplayer(DM) attributes in weapons .tik file(in this case springfield.tik) looks like that:
// DM Attributes
dmstartammo 50
dmammorequired 1
// dmfiredelay 1.25
dmfiredelay 2.0 // this is the firedelay that is actually incured due to the animations
dmbulletrange 4000
dmbulletspread 59 59 140 140
dmzoomspreadmult 0.055
// dmbulletdamage 100
dmbulletdamage 106
// dmmovementspeed 0.77
dmmovementspeed 0.8
dmcrosshair 1
Ver, delete all mods in your folder and start from beginning please by adding mods one by one. You can also tell what other mods you have installed in server. Also in case you don't know this, you have to restart your server in order to make changes/added mods work, or stop it, add mods, and start it again.
