ICS-321 CS4 R.I.S. EBB Airsoft Rifle
Feel the power of precision engineering in your hands. The ICS-321 CS4 R.I.S. EBB is built to dominate every skirmish—from tight urban CQB to wide-open woodland battles. At its core lies ICS’s proprietary split gearbox: a breakthrough design that lets you strip, inspect, and upgrade your rifle faster than ever. Combined with a realistic electric blowback (EBB) system, every trigger pull delivers satisfying recoil feedback and audible rat-tat-tat, immersing you in the thrill of real-steel shooting.
Crafted from full-metal components, the CS4 offers rock-solid durability and a reassuring heft that stabilizes your aim, while a 263 mm inner barrel keeps your shots tight and on target. The full-length RIS handguard provides ample 20 mm rail space for optics, lights, grips, lasers—whatever you need to create your ideal setup. An adjustable crane stock lets you dial in your cheek weld and length of pull for complete comfort under fire.
Under the hood, a high-torque motor and beefy M120 spring propel 0.20 g BBs at a blistering 395 fps (120 m/s), delivering consistent range and penetration. With a massive 450-round polymer magazine, you’ll outlast most opponents before needing a reload. Power comes from either a 9.6 V Ni-MH or an 11.1 V Li-Po battery (small connector), giving you the flexibility to choose your preferred chemistry and voltage.
Whether you’re new to airsoft or a seasoned veteran, the ICS-321 CS4 R.I.S. EBB combines user-friendly serviceability with battlefield-ready performance. The split gearbox design transforms maintenance from a dreaded chore into a quick roadside swap, so you spend more time playing and less time wrenching. Rugged, reliable, and ready to rock—this is the airsoft rifle that works as hard as you do.
