Classic br rarity

I was looking at the new reqs from cartographer’s gift, and I noticed the classic (I think it just means it has the classic scope) br has different rarities based on the add-ons (normal is common, bayonet is ultra rare and others are uncommon) I think the other loadout weapons have rarities based on the scope, so do you know if they’re changing the older ones too, or will this just be for the ones that are coming up?

I think it’s the same way with the Recon AR, The scope and the add-ons are uncommon up to the bayonet. Don’t take my word for it, I’m about as clueless as you are.
