Description: The B&T GL-06 is a fully licensed replica grenade launcher, originally made by the Brugger & Thomet, Switzerland. The stock and receiver are made of polymer and the barrel and front guard are metal. All four side rails are metal and will support any accessories imaginable. A quick-remove front grip is supplied to make the GL-06 complete. The GL-06 launcher takes any length airsoft grenade, which is a device that looks like a real world grenade launcher but uses a gas propellant to fire a variety of projectiles, like large amounts of 6 mm BB's. When inserted in a grenade launcher, and fired, it shoots all the BB's at once with a big blast, great for room clearing and suppressive fire.
