👉 The bp weapon, also known as the Bipolar Transfer Weapon or BWP, is a compact and highly portable submachine gun designed for close-quarters combat. It features a unique dual-action mechanism that allows it to switch between a pump-action and an automatic firing mode with minimal recoil. The weapon uses a bipolar transfer system, where the magazine is mechanically split in half to feed rounds into the chamber, enabling rapid reloading and sustained fire. Its compact size and lightweight design make it ideal for military and law enforcement use, offering a balance of power, mobility, and ease of use in tight spaces.
