 All exterior metal surfaces are phosphated for corrosion resistance and then coated with a black enamel (except for the barrel, gas block and front sight tower).The machined solid steel billet action avoided cracking problems the AK-series had with steel stamped sheet actions, but this made the Galil heavier.The Gas-Block, handguard retainers and folding-stock mechanism components are cast pieces that are finish-machined and accordingly fitted.
