This guide will let you know how to UNLOCK BAS P SMG in Warzone 2 & MW2 (Battle Pass).
You have to boot up your game and then select battle from the top of your home screen. From here, you need to select the A6 which will give you the BAS P SMG. To unlock this, you have to claim all four rewards here in A6 and then you will be able to use the base version of the BAS P.
If you don’t have a purchased battle pass for this, then you can also unlock it for free. For this, you have to select AO from the bottom of the screen and claim all four rewards from here. Then you will be able to unlock the top reward which means you must have 5 tokens. After that, it will unlock A1 and you have to claim all four rewards here and then you will unlock A2 and A3 regions. After that, unlock A6 and you will get the BAS-P.
You can also unlock this by going into the DMZ and then unlocking the sniper from there permanently. If your friends drop it, then you have to pick it up in the DMZ, and exfil. Then you will get the BAS-P permanently.
