Reload animations working fine in SP, but not working at all in MP?

EDIT: Problem solved, the server just needed the models too.

Hi FP. I’ve been puzzling over this glitch for quite some time and can’t think of a solution. What happens is peculiar, when using this model (I apologise to whomever’s pack it is from) reload animations play fine in singleplayer, but not at all on a server. This does not occur for any other models e.g. CS:S or HL2 weapon models, they function fine online and singleplayer.
Here is the test code I am using:

if ( SERVER ) then

	AddCSLuaFile( "shared.lua" )

SWEP.PrintCycle				= true //Shows up in console the current cycle when reloading for timing reload noises

SWEP.ViewModelFlip			= true
SWEP.HoldType				= "ar2"
SWEP.PrintName				="anim tests"

SWEP.ViewModel				= "models/weapons/v_adv__ar.mdl"
SWEP.WorldModel				= "models/weapons/w_586.mdl"

SWEP.Weight					= 5
SWEP.AutoSwitchTo			= false
SWEP.AutoSwitchFrom			= false

//SWEP.ZoomLevel				= nil //Reduce FOV to this when zoomed

SWEP.Primary.Sound			= Sound( "newsstrp/MORITANEW.wav" ) //Firing sound
SWEP.Primary.Recoil			= 2 //Upward recoil
SWEP.KickMax				= 0.3 //How much we are allowed to kick
SWEP.KickMult				= 5 //How fast we get to max kick

SWEP.Primary.Damage			= 20
SWEP.Primary.NumShots		= 1

SWEP.Primary.DefaultCone	= 0.013 //Sighted cone
SWEP.Primary.ConeUnsighted	= 0.2 //Hipfired cone
SWEP.Primary.ConeRunning	= 0.5 //Sprinting cone

SWEP.Primary.Delay			= 0.11 //Delay between shots

SWEP.Primary.Automatic		= false

function SWEP:SecondaryAttack()


function SWEP:Reload()		

This is for a friend and I’m trying to push these guns out as quickly as possible, please help fp!
edit: this actually happens with all weapon models now it seems
