ADZZZYs Armoury features a G&G FN2000 AEG repair... "This rifle was in need of a new tappet plate as it had worn causing it to not feed BBs. Simple fix and a few upgrades later and this AEG is back up to full performance. The spring guide on this G&G FN2000 allows for easy adjustment of its FPS just by screwing and un screwing the guide itself."
