  • Full metal construction
  • Ultra-short version - Great for CQB
  • Mounts to 20mm Picatinny rails 

If you need more firepower without extra length, the A&K M203 40mm MOSCART Grenade Launcher; Super Shorty is ideal. Based on the real steel M203 grenade launcher used by Arnie in Predator and serving with the US Army from the late Vietnam War right up until the present day, this M203 is the "Super Shorty" version, even shorter than the "Short" version and ideal for compact SMGs and short-barrelled rifles. The pre-installed mount is a QD example for 20mm Picatinny rails, meaning you can quickly mount it and remove it in seconds depending on the situation at hand.

Like other Airsoft M203s, the A&K Super Shorty uses 40mm MOSCART grenades as a power source and will require at least 1 grenade to function. Most MOSCARTs work like a giant shotgun, sending between 18 and 140 BBs downrange with a single pull of the trigger with a game-dominating spread, though specialised MOSCARTs which shoot different payloads are available. If you want to give your primary a more aggressive look with a firepower increase as a bonus, the A&K M203 40mm MOSCART Grenade Launcher; Super Shorty will give you what you need!

    • M320A1 - US Army and UKSF issued
    • 40mm MOSCART grenade launcher
    • Stand-alone or weapon-mounted via 20mm rail

    If you feel the need to arm yourself with a "noob tube" for Airsoft, a fine replica of the latest and greatest 40mm grenade launcher to be issued to both the US Army and UK Special Forces will be of interest! The S&T M320A1 is a highly modern launcher sporting ambidextrous functionality, side mounted grenade launcher ladder sights and robust yet relatively lightweight construction.

    The true benefit of the M320 platform is that it can be used either as a stand-alone launcher, with its included sliding adjustable stock, or as a weapon-mounted launcher with the stock removed to reveal its integral 20mm Picatinny mounting apparatus. Swapping between the two configurations takes mere seconds, so if you are the indecisive type of grenade launcher user this will suit you well!

    • For AR36K/E Replicas

    • Underbarrel Launcher w/handguard & ladder sights

    If you need a gun on your gun so you can shoot while you shoot, the S&T G316 Grenade Launcher is ideal! This imposing piece of equipment is designed for AR36 platform Airsoft guns, and will install in place of your handguard to provide an awesome under barrel 40mm Grenade Launcher for you to effortlessly fire Airsoft MOSCART Grenades from underneath your Assault Rifle. 

    The included handguard is designed to replace either the K or the E (full-length) AR36 handguards, so if you want to add it to your AR36C you will most likely need a barrel extension to clear the handguard. If you want a serious firepower upgrade for your AR36, then the S&T G316 Grenade Launcher is just what you were looking for!
