Let's do this systematically, if your names are different try these :

Your turret is named "TURRET01". You have it linked to your model's base or chassis.

You name the FireFXBone "MUZZLE01", the barrel "BARREL01". WeaponLaunchBone is the same as FireFXBone. Muzzleflash is fine.

Your code says:

DefaultConditionState 
      Model               = AWMNTIGERII 
      Turret              = TURRET01
      WeaponFireFXBone    = PRIMARY MUZZLE <- no need for numbers, the game will go through all available muzzle bones, say MUZZLE01 to MUZZLEnn
      
      WeaponMuzzleFlash   = PRIMARY MuzzleFXTG 
      
      WeaponLaunchBone    = PRIMARY MUZZLE <- no need for numbers, the game will go through all available launch bones, say MUZZLE01 to MUZZLEnn
      
      WeaponRecoilBone    = PRIMARY BARREL <- no need for numbers, the game will go through all available recoil objects, say BARREL01 to BARRELnn
      
      WeaponFireFXBone    = SECONDARY Muzzle02 
      WeaponMuzzleFlash   = SECONDARY MuzzleFXMG 
      WeaponLaunchBone    = SECONDARY MuzzleMG 
      WeaponRecoilBone    = SECONDARY BarrelMG 
    End
