There probably isn't a star category for the SA-18 because it's a canceled support weapon. It's a shame that they will unlikely consider bringing it back.

On the other hand, asking for the star category for the SA-18 is like asking for the star category of the Baguette Gun, CQBR Devgru, Fish Gun, and the SD Gun.

However, I can definitely tell you that the M419 Combat CQB SE CAMO Black MOD LE MARK II is a 5 gold star weapon.
