The E&C M203 grenade launcher is a faithful full-metal replica of the iconic Colt M203, engineered for serious milsim and skirmish play. This long-barrel variant delivers authentic proportions and robust construction suitable for demanding airsoft operations.
Key Features
- Full metal construction – durable and field-proven finish
- Long barrel configuration – improved accuracy and air volume for effective range
- 40mm moscart shell compatibility – use gas or CO2 charged rounds filled with BBs
- 3-mount platform set – attaches to various rail systems and receiver types

Real-World Use Cases
This grenade launcher excels in milsim events where suppressive fire and area coverage matter. The three included mounts let you swap between primary rifle platforms without purchasing additional adapters, ideal for players rotating loadouts across multiple weapons. Skirmishers favour the moscart’s psychological impact and BB dispersal pattern for mid-range engagements.

UK Legal & Site Notes
As a spring-powered or gas-powered launcher, the M203 is an airsoft accessory unrestricted under UK airsoft site rules. Always confirm your site’s grenades and launcher policy, as some venues restrict explosive-effect toys. The launcher itself fires standard BBs via moscart shells, keeping you compliant.
