In the neon city of cyberpunk, the PP-19 "Buffalo" submachine gun has become the preferred weapon for street warriors and private security with its unique futuristic feel and practicality. This submachine gun has been redesigned to meet the combat needs of high-tech environments, and its surface is covered with a corrosion-resistant nano coating that can maintain performance in acidic rainwater and electronic smoke. The 64 round spiral barrel has been upgraded and can now carry specially designed high penetration ammunition, suitable for penetrating enhanced bulletproof vests. Equipped with advanced aiming systems, including infrared night vision and thermal imaging functions, it can accurately shoot even in low light or completely dark environments.
