The “Pro” Take
A valve key isn’t the sort of tool you necessarily think about until you actually need one. Once a GBB magazine needs a valve replacing or removing, however, having the correct tool can save a lot of frustration.
The Unicorn Stainless Steel GBB Valve Key gives you a dedicated tool for the job, rather than trying to improvise with pliers, screwdrivers or other tools that can damage the valve or surrounding magazine components.
For anyone who regularly runs GBB pistols, rifles or spare gas magazines, this is exactly the sort of inexpensive workshop tool that’s worth having in the kit before you need it.
GBB Maintenance & Installation
Before working on a gas magazine, make sure the magazine is completely depressurised and that there is no gas remaining inside. Use the valve key carefully and make sure it is properly seated on the valve before applying force.
When reinstalling a valve, avoid excessive force. Valve threads and magazine bodies can be damaged if the tool is not correctly aligned or the valve is overtightened.
