Today I will share with you one more review, initiated Powered by MadBull airsoft – X Factor Piston full teeth. Again, if you do not know what is piston or what its function is – the next paragraph you might find uninteresting. This review is for those who know what we are talking about.
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) ;)
