Some short news from Echo1 USA Airsoft. What is in the works right now is a full metal M4 with 8mm bearing, steel gear setup, convertible outer barrel, and enhanced hop up. No details yet on pricing and release date indicated. Hopefully, they send further details and clearer photos soon as what we have for preview doesn't show much detail. Still, another full metal M4 to be introduced in an already crowded M4 airsoft replica market.
