Union Fire M4 hi cap Black charger

Union Fire Hi Cap airsoft magazine designed for M4 platforms. This airsoft magazine has a capacity of 300 6mm BBs. The spring with which the airsoft magazine is equipped is capable of feeding the vast majority of BBs without the need for winding. It is made of metal, while the internal mechanism is made of plastic.

Operation

Open the top cover, pour BBs into the opening, close the cover, and arm the internal spring with the bottom wheel. For proper functioning, it is recommended not to overwind this spring. BBs can be stored inside the airsoft magazine but without tensioning the spring. To release the spring tension, point the mouth of the magazine towards a BB recovery space and press the button near the BB exit point.

Attention! Do not pour silicone oil inside. This greasing process is incorrect and jeopardizes the accuracy of the BBs, dirtying the HopUp rubber with silicone oil.
