Grenades

Recently I used a grenade launcher. It was a grenade pistol (see bottom) Its Boss. Like the 6 barrel grenade launcher is also boss but is over priced $400 TO 800. There are many different stiles. The grenade pistol is a 1 shot but only $200.
The cool thing about the grenade pistol is that you could hook it to your gun.
