This is a metal gearbox, full AEG rifle. Version 2 metal mechbox, standard AEG V2 internals, and collapsible rear stock. Uses M4 parts and spare magazines. Polymer furniture for a lightweight build. This weighs a bit less than the full metal version, but still has a strong gearbox and shoots great. This is the best valued, yet reliable, FN SCAR-L on the market.
