The Echo M16, modified by the Alliance weapons expert 'Dajiao' from the base M16. After modification, the gun's range was reduced by 30% and was limited to single-shot firing. In exchange, its accuracy was slightly improved, noise was significantly reduced, and it featured a flash suppression effect. However, being a modified gun, it did not allow any additional attachments such as silencers, compensators, or extra magazines beyond the built-in 2x scope. The silence value is 90, with the gunshots audible within 5 meters.
This Echo M16 can be said to be a highly characteristic assault rifle, Lin Wu felt that the rifle alone was worth today's pay. Lin Wu reported, "Sniper taken down." During the second corpse looting, Lin Wu only managed to retrieve 10 rounds of 5.56 ammunition.
