M203 Under‑Barrel Airsoft Grenade Launcher (Short / LMT Style)

Experience the unmistakable presence and theatre of a true 40mm under‑barrel launcher in airsoft form. This M203‑style launcher delivers an authentic loading, slide, and eject action with full metal construction and LMT‑style markings — built to look, feel, and operate like the real piece while staying safe for game use. It’s ideal when you want the psychological and tactical advantage of a dedicated room‑clearing device without adding bulk to your build.

Designed to mount quickly beneath M4/M16‑type rifles (and many other platforms with a 20mm rail) via the quick‑detach mount, the short tube format keeps things compact and manoeuvrable for CQB and skirmish play. When paired with airsoft grenades that use a gas propellant, the launcher releases a wide spread of 6mm BBs — a dramatic, effective option for suppression and clearing confined spaces.

The unit features rifling inside the tube for authenticity, positive grenade retention when loaded, and an ejector that holds spent grenades during opening. Safety and handling are thoughtfully addressed with a forward safety lever, a fitted trigger guard, and a robust slide‑back opening action that reproduces the handling of the military design.

Whether you’re building a realistic kit or want an attention‑grabbing tool for team tactics, this M203 replica balances realism, reliability, and compatibility — all in a short, all‑metal package.
