The D-Boys M203 Long under‑barrel grenade launcher is a detailed and functional replica of the iconic American M203, designed specifically for use with M4/M16 airsoft rifles. It features a versatile mounting system and excellent compatibility with modern tactical handguards.
The set includes three mounting options: two barrel clamps for installing directly onto the outer barrel, and one Picatinny (RIS/RAS) adapter. This allows the launcher to be mounted on both standard M4/M16 barrels without rails and on any rail-equipped tactical handguard.
The launcher uses standard 40 mm gas shells (one Green Gas 18BB shell included). These shells are charged with Green Gas and can fire dozens of BBs in a wide spread — ideal for close-quarters battles, room clearing, and gaining tactical advantage.
The body is made from a combination of silumin alloy, steel, and durable ABS, providing a solid balance between weight and strength. Its length is 390 mm, weight — 1.75 kg, giving the platform realistic handling and stability. Fully compatible with Pyrosoft G203D shells and other common 40 mm cartridges.
