Abstract: An airsoft adapter assembly capable of being removably attached to an airsoft magazine and an airsoft reservoir. The airsoft adapter links an airsoft magazine to a reservoir to allow for interchangeability for attaching different types of reservoirs to an airsoft gun magazine or for attaching the same reservoir to several different configurations of airsoft guns and their coordinating magazine. The airsoft adapter makes a sufficiently airtight seal for high performance projectile shooting with improved projectile conduits and pressurized flow conduits.
