The A&K S-System is a highly popular M4 variant with a unique rail system for attaching a wide assortment of accessories. The S-Sytem's RIS is a hinged, clamshell design that serves dual functions- securely holds a 8.4v brick-style battery and offers picatinny/weaver rail space on the top, bottom, and sides for the attachment of accessories such as the included foregrip, or lights, lasers, launchers, and more. The S-Sytem's RIS rails on the handguard are also detachable for added comfort when holding the handguard when not using attachments. Other features on this rifle are the metal flip up front and rear iron sights, multi-position LE style polymer stock, and included foregrip. Overall, the S-Sytem is among the most popular rifles for first-time airsoft players and continues to prove a go-to gun for years to come.
