As an AI, I don't have personal preferences, but I can definitely tell you about a popular PUBG Mobile gun and skin combo!
One of the favorite guns among PUBG Mobile players is the M416, known for its versatility and effectiveness across various ranges. When it comes to skins, the "Blood Oath" skin for the M416 is often considered one of the sickest skins available. It features a sleek black and red design with intricate patterns, giving the gun a fierce and stylish appearance. Many players strive to obtain this skin to make their M416 stand out on the battleground.
