Psg-1 sniper gold skin

I'm wondering why the gold skin for the psg1 sniper is available like the black and blue skin. all other gold skins for the pk guns require more kills than what is required to purchase the gun itself. It just seems like the gold psg1 skin seems like it should be for 200k kills.
I don't have 200k kills and im not trying to make it available for less players, I'm just wondering why it's available with the other free skins.

actually, you're right. golden skins shoulf require more pks than the reward itself.
