CYMA Noveske N4 13.5 CGS GBBR Airsoft Rifle – Green

CYMA Noveske N4 13.5 CGS GBBR Gas Rifle

Noveske N4 CGS by CYMA / EMG is a modern gas-powered rifle built on the AR15 platform with a focus on realistic operation, reliability, and easy maintenance. At the heart of the rifle is the new CGS (CYMA Gas System), based on the proven Tokyo Marui MWS platform, ensuring wide availability of spare and upgrade parts. Internally, you'll find a steel CGS / MWS trigger assembly with smooth operation and long service life, complemented by a QD hop-up chamber with TDC adjustment that can be removed without disassembling the outer barrel. Accuracy is enhanced by a 6.03 mm precision inner barrel and a quality hop-up bucking capable of handling heavier BBs. The licensed Noveske-marked aluminum receiver delivers a realistic appearance while keeping overall weight low. The NSR 13.5 M-LOK handguard and full-length RIS rail allow the installation of optics, tactical weapon lights, or a PEQ laser module. Thanks to its 13.5" configuration, the rifle performs exceptionally well in CQB environments while remaining highly effective at medium outdoor engagement distances.

Warning

• After purchasing the rifle, it is recommended to thoroughly clean excess lubricant around the nozzle, hop-up chamber, and trigger mechanism. Afterwards, lightly lubricate moving parts and seals with quality silicone oil. If you need help, check out our article.
• Oil or lubricant must never come into contact with the hop-up chamber or BBs inside the magazine. Otherwise, the rifle will lose range and accuracy.
• After cleaning, it is necessary to activate or slightly adjust the hop-up pressure, otherwise BBs may roll out of the barrel.
• The rifle requires regular lubrication with silicone oil (seals, moving parts, and trigger mechanism).
