Which is the BEST AX50 Sniper Rifle Blueprint in Modern Warfare?

I have been using my sniper rifle for a while in COD Modern Warfare multiplayer and co-op games. So far AX50 is my favorite one, but I need the best available blueprint for this. The ones you can buy or the ones you can get by completing missions or challenges. I think the Battle Pass didn’t have any AX50 ones.

Do kindly let me know, please!
