How do you unbox an item with no box? Well, find out in this 4UAD Smart Airsoft ASMR session with the VFC M249 Gas Blowback. This is the first GBB machine gun that works like a real one. It has a light metal body and bolt, and a 100-round magazine. You can take it apart and put it back together. It also has a hop-up, a bipod, and shoots 6mm BBs with HFC134a gas. Should be shipping to sellers worldwide.
