All the reviews will tell you so simply because A&K is the OEM manufacturer for all the other M60s on the market. Which means "better performance" at a "better price". It is reliable, realistic, nicely finished, accurate, powerful, easy to upgrade/repair and super affordable (considering the not as good models used to retail for $1000). This M60 is a replica of the heavy machine gun used by U.S. special force troops in real combat to supply heavy firing. It is equipped with a super capacity box magazine and is commonly used to secure an area or to provide serious heavy firing in Airsoft combats. The A&K M60 is full metal with built in bipod and redesigned 8mm gearbox and hop-up chamber. It is an out of the box ready to go heavy firing support machine gun! The TOP, CA and other M60 normally costs from $600 ~ $1000 without the box magazine, reliability and upgrade-ability!
