Is COV Early Adoptor Weapon Unique?

I did a check online and found out that the COV Moar Inespensuv Shreddaa has other variants that are also Shreddaa such as the Bruisin Shreddaa.

Was wondering if the COV Adopter Weapon (Inespensuv Shreddaa) is unique to the early adopter pack or can drop in game randomly as well?

As far as I know only the Dangerous Vault Hero (the legendary Maliwan SMG) was exclusive as a VIP gun. Don’t quote me on that though.

I saw a version of this in my inventory a day or two ago, though whether it was a world drop or manufacturer reward (if COV even does that) or however I ended up with it I’m not certain.
