A short teaser from SCDTV showing their review of the E&L Airsoft M4A1 AEG done in cooperation with Gunfire, the distributor of E&L Airsoft products in Europe. We are not sure if this the DX version, built with steel, aluminium allow and some plastic parts. The battery is a stock tube type and usually has an initial muzzle velocity of 400-420fps on 0.20g BBs.
