The S-Class series by ARES is designed to provide an authentic airsoft gun experience for any level player. The M4A1 CQB RIS features an exact 1:1 MK18 design that is commonly used by various groups in SOCOM. The upper & lower receiver are made out of extremely tough nylon-fiber polymer, while most other external parts are made out of aluminum alloy (metal). The metal parts include the rail system, barrel, buffer tube, iron sights, mock bolt, charging handle, trigger, and more. With the materials used, ARES has produced an incredibly solid airsoft M4A1 CQB that is sure to measure up to the test of time. Internally, this airsoft gun features a metal reinforced gearbox, a high torque motor, a 255mm x 6.04mm tightbore inner barrel, and an adjustable hop-up unit. The tightbore inner barrel increases the maximum range, accuracy, and velocity, allowing this airsoft gun to be used in field environments as well. For a reliable airsoft primary, the ARES M4A1 CQB is the best in its class.
