King Arms M79 Grenade Launcher (KA-CART-04)

The Iconic Springfield Armory "Thumper"

There are few weapons in military history as instantly recognisable as the M79 Grenade Launcher. Originally developed by the Springfield Armory in the late 1950s to bridge the tactical gap between the throwing distance of a hand grenade and the maximum range of a mortar, it became a defining weapon of the Vietnam War. Affectionately dubbed the "Thumper" or "Bloop Tube" by American troops due to its distinctive firing sound, the M79 is a true legend of 20th-century warfare. The King Arms M79 (KA-CART-04) beautifully captures the spirit of this historic firearm, delivering a visually striking and highly functional airsoft replica.

Museum-Quality Wood and Metal Build

King Arms is globally renowned for its exceptional external craftsmanship, and this M79 is a testament to that reputation. The stock and handguard are carved from beautiful, high-quality real wood that boasts a rich grain and a smooth, authentic finish—perfectly mirroring the original military-issue aesthetics. Paired with this is a full-metal receiver and an aluminium alloy barrel, which provides a highly realistic weight without making the launcher overly front-heavy. Every detail has been carefully considered, from the heavy-duty rubber butt pad designed to keep the weapon shouldered securely, to the fully functional folding ladder leaf sight used by grenadiers for calculating high-arc trajectories.

Versatile 40mm Airsoft Firepower

The true beauty of the King Arms M79 lies in its incredible versatility on the field. It operates via a simple, ultra-reliable break-open mechanism, just like a classic single-barrel shotgun. Simply push the barrel release lever, drop in a standard 40mm airsoft gas grenade shell, snap it shut, and you are ready to fire. Because it is compatible with almost all standard 40mm MOSCART shells on the market, you can tailor your loadout to the specific mission. Load up a massive 120-round shower shell to instantly clear a room in CQB, or utilise specialised shells for launching foam projectiles at enemy vehicles during large outdoor mil-sims.
