We have learned of the robustness of the AK AEGs from E&L Airsoft from other airsoft videos, and Jag Precision, the exclusive distributor for E&L Airsoft wants to find out first hand... "The E&L Airsoft AK is the most robust airsoft rifle on the market. To prove it, we dropped it off a three story warehouse and testing whether the E&L rifle would still shoot. We followed that up by using another E&L by playing with in the mud."
