AirTac Gen 2 ABS CRBN Upper Custom-Built for Performance

The AirTac Customs CRBN Gen 2 Upper Receiver System redefines performance and style for airsoft enthusiasts seeking a lightweight yet rugged upgrade. Crafted from real carbon fiber and impact-resistant ABS polymer, this upper delivers unmatched durability while shedding excess weight—perfect for builds demanding both strength and agility. Designed with user convenience in mind, its modular design allows seamless part swapping between CRBN Gen 2 uppers, making customization quick and hassle-free.

A standout feature is the integrated fiber-optic front sight, available in green or red, which enhances target acquisition in diverse lighting conditions. With a sleek CNC-milled finish and seven vibrant color options—from matte black to bold gold—this upper offers both functional upgrades and aesthetic appeal for personalized builds.

Compatibility is key: it works seamlessly with Polarstar Fusion Engines (drop-in ready), V2 HPA systems (F2/Jack/Inferno/N7), and G&G polymer lowers (SSG1/ARP9), while also fitting Monk Customs and EMG F1 lowers with minor adjustments. However, it’s exclusively paired with MAXX Hopup Chambers (ME/M4P/M4A) for optimal performance—a detail critical for precision-focused players.

Whether you’re upgrading an existing setup or building from scratch, the CRBN Gen 2 Upper combines cutting-edge materials, ergonomic design, and cross-system adaptability to elevate your airsoft experience without sacrificing style or reliability.
