The ICS Grenade Launcher is not only one of the best and most reliable but also on of hte most affordable on the market. Made out of a reinfored polymer these are not only sturdy but light to make it easier to carry. ICS also offers their ICS 203 Grenade Shells that are very straight forward and as afforadble as the launcher itself. Between the ICS Grenade Shells and the ICS GLM Six Shot Grenade Launcher you can have a very effective squad ending airsoft gun.
The Grenade launchers in airsoft are used with both the BB shower method of filling the shells with BBS and foam projectiles. Typically they have a range of 10-15 ft in a game. For this reason a grenade launcher can really change a game, end a skirmish and make the other team fear the ICS GLM.
