CYMA / EMG Noveske N4 13.5" CGS GBBR Gas Blowback Rifle – Green
The CYMA / EMG Noveske N4 13.5" CGS GBBR is a premium gas blowback airsoft rifle that combines realistic operation, licensed Noveske styling, and outstanding upgrade potential. Built around the new CYMA Gas System (CGS), which is based on the highly respected Tokyo Marui MWS platform, this rifle offers excellent reliability, realistic recoil, and compatibility with a vast range of MWS aftermarket parts.
Featuring a lightweight licensed aluminum Noveske N4 receiver, a 13.5" NSR M-LOK handguard, and a precision 6.03 mm inner barrel, the N4 delivers impressive accuracy and fast handling. Its versatile 13.5-inch configuration is equally at home during CQB games and medium-range outdoor engagements.
CYMA CGS – The Next Generation Gas System
The innovative CGS (CYMA Gas System) is designed around the proven Tokyo Marui MWS architecture, providing exceptional reliability while maintaining compatibility with many popular upgrade components. The rifle features a durable steel trigger group with smooth trigger pull and long service life, making it suitable for intensive skirmish use.
The QD Hop-Up chamber allows quick removal and precise TDC adjustment without removing the outer barrel, making hop-up tuning faster and more convenient than traditional GBBR systems.

MWS Compatibility & Upgrade Potential
The CGS platform has been engineered for broad compatibility with the Tokyo Marui MWS ecosystem. Magazines, bolt carrier groups, nozzles, trigger assemblies and most external AR-15 components are fully interchangeable, allowing easy customization and access to one of the largest GBBR aftermarket platforms available.
The only major exception is the proprietary QD TDC Hop-Up chamber, which offers improved adjustment and differs from the standard MWS design.
Built for Serious GBBR Players
Delivering approximately 1 Joule of muzzle energy (around 100 m/s with 0.20 g BBs), the rifle performs best with 0.28 g to 0.32 g BBs, providing excellent consistency and stable flight. Combined with its realistic recoil, ambidextrous AR ergonomics, and premium construction, the Noveske N4 CGS is an outstanding choice for both experienced gas rifle users and players looking to upgrade from an AEG.
