The ACETECH Volcano Grenade Launcher is a 40mm airsoft grenade launcher and the first of its kind to feature a built-in, rechargeable tracer unit with a simulated muzzle flash effect. It is a versatile, modular device used for airsoft gameplay. 
 
Key Features
Integrated Tracer & Flame Effect: The main feature is the built-in LED tracer unit, which illuminates compatible green and red tracer BBs as they exit the barrel. It also has seven different color modes for the "flame" (muzzle flash) effect, which can be changed with a button.
Versatility: The launcher can be used in several configurations:
Standalone: Used as a large pistol-style launcher with its included grip.
Rifle-mounted: It can be mounted to a rifle via a 20mm Picatinny bottom rail after removing the grip or stock.
Customized: It has Picatinny rails on the top, bottom, and sides for adding accessories like optics, foregrips, or lasers.
Compatibility: It is compatible with most standard 40mm airsoft MOSCART (multiple-shot cartridge) grenade shells on the market. Acetech recommends using their proprietary "AceHive" shells, which are designed for quick reloading using the "Spawner" speedloader.
Power & Controls: The tracer unit is powered by an internal LiPo battery that is rechargeable via a USB-C port. It features intelligent power control, turning on when shaken and entering sleep mode after five minutes of inactivity.
Build: The main body is constructed from robust, high-density nylon fiber polymer, making it lightweight yet sturdy.
