Engineered for Airsoft Maintenance
The handle is manufactured from forged 6061-T6 aluminium with a durable anodised finish, providing excellent strength whilst remaining lightweight. As a result, the tool remains comfortable to use during extended maintenance sessions.
The valve tools are produced from heat-treated 1144 medium carbon steel with a hardness of approximately 47 HRC. Consequently, they offer excellent wear resistance and durability for repeated use on gas magazines, valves and related components.
