Tag: Spring guide

Dear friends,

we have another review, powered by MadBull airsoft. This time it is  –  Spring Guide (the spring root – others may say) for V2 gearbox. Who does not know what it is, how it works, or looks like – do not read further. However, the next time you change spring guide, ask for a better one – Madbull Ultimate Spring Guide (take a note) ;)
