Airsoft GI has something for those who like launchers, especially standalone ones... "The Ares Stand Alone Launcher is the proper way to mount an M203 separate from your primary weapon. This Stand Lone M203 system is great for reducing weight on your main weapon, but still keeping the power of the M203 close at hand. The EGLM is equipped with rails on all 4 sides, the bottom is reserved for the EGLM, the top for the included iron sight, and the two sides for whatever your heart desires. There is also a pistol grip and retractable 4 position for comfort while firing."
