ICS CXP‑MARS Carbine S3 Gen2 — Compact EBB AEG
The ICS CXP‑MARS Carbine S3 Gen2 (ICS‑302S3) is a modern, ambidextrous M4‑style AEG built for skirmish players who want a full‑metal feel with up‑to‑date internals. Its ergonomic keymod/MLok handguard and adjustable length make it a nimble carbine for CQB while retaining a roomy battery compartment and robust full‑metal construction. icsbb.com+1
Under the receiver you’ll find ICS’s Split Gearbox with QD spring guide and the SSS/3S electronic trigger system for crisp, consistent trigger response and pre‑cocking capability. The rifle ships with an EBB (electric blowback) system for realistic bolt movement and an electronic trigger suite (SSS/3S) that supports fast reflex firing modes. Battery and charger are not included. icsbb.com+1
Performance is tuned for field use — the 375 mm barrel and factory setup produce roughly 120 m/s (≈394 FPS) out of the box, putting this model in the higher‑power AEG bracket and meaning recommended battery choices differ from lower‑FPS AEGs. The long‑axle motor and high‑capacity 300‑round magazine give this carbine the sustained fire you need for aggressive play. bntonline.co.za+1
Built to be player‑serviceable, the ICS CXP‑MARS S3 Gen2 combines realistic feel, upgrade potential, and modern electronics so it’s a great baseline for players who want a reliable out‑of‑the‑box performer or a platform to tune. icsbb.com
