HI! I was thinking of buying an m14 and converting it into an m21.
I would like to put a guarder sp17 spring inside and was wondering if someone can help me with what to put inside.
I was thinking of putting guarder piston, cylinder, cylinder head, nozzle and systema piston head inside.
I would also put element 300% torque up gears for m14 and a systema magnum motor in there. A 11.1 volt li-po battery would power all of this.
Now, would these upgrades be enough to pull that sp170 spring or will parts start to break soon?
