Our take: The Madbull JP Gas Block Kit is truly one of a kind in the airsoft world. It allows you to have four different lengths of outer barrels without having to buy each one individually for a steeper price. Even though it’s a two-piece barrel, the Madbull JP Gas Block Kit uses large threads and a set screw to achieve the sturdiness of a one-piece barrel. It’s lightweight in comparison with other one-piece barrels and is constructed with aluminum. This kit will allow you to use almost any rail system on the market and to be able to switch outer barrels at any time without the hassle of removing the rail system first.
