SA-VGS4 VAPOR™ 870 Tactical GNB Shotgun - Black / Tan

Specna Arms VAPOR™ Series Shotguns

Looking for a compact and lightweight pump-action shotgun for CQB scenarios? Want to use realistic 30 BB shells? Need a reliable gas-powered system with the option to shoot 3 or 6 BBs per trigger pull? Then the Specna Arms SA-VGS4 VAPOR™ is exactly what you’re looking for. Designed as a universal CQB shotgun, it combines metal structural parts with durable polymer components for a realistic feel and strength. Powered by Green Gas stored inside the stock, the gun delivers stable performance and consistent pressure. The reinforced nozzle ensures durability and reliable gas flow. Beneath the shell ejection port is a selector switch allowing you to choose between 3 or 6 BBs per shot. A safety button prevents accidental firing, while a lock button secures the shell port. The VAPOR™ shotgun is built for fast handling in tight CQB spaces, smooth reloading, and powerful, consistent performance. The SA-VGS4 model features a classic ergonomic handguard and a top RIS rail for mounting a red dot sight. It’s equipped with a fixed M870-type stock with rubber buttpad, housing the gas fill valve.
