Our performance packages are the industry standard everyone else is chasing — if you want something that’s going to outperform everything else on the field, this is it.\u003c\/p\u003e\n\u003cp\u003eThe \u003cstrong\u003eQCU\u003c\/strong\u003e (Quick Carbon Upper) is a premium, competition-ready HPA platform developed collaboratively by Gorilla Airsoft Technology and MAC Airsoft, then built and tuned by KA Tech. Engineered specifically for speedsoft and CQB, the QCU is favored for its ultralight carbon fiber construction, lightning-fast trigger response, and on-the-fly adjustability.\u003c\/p\u003e\n\u003cp\u003eThese custom builds feature a CNC-machined receiver and a proprietary TDC hop-up, and are compatible with HPA engines like the PolarStar F2 or Jack. Because they’re modular, you can extract the engine and fire control unit (FCU) in seconds without disassembling the entire gun.\u003c\/p\u003e\n\u003cp\u003eFinished in a \u003cstrong\u003eRed Forged Carbon\u003c\/strong\u003e colorway.\u003c\/p\u003e\n\u003cp\u003eBuilt with a \u003cstrong\u003e141 mm tight-bore inner barrel\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cp\u003eColors, CNC design, and specific requests can always be customized — just reach out.\u003c\/p\u003e\n\u003cp\u003eThis is one of our refurbished rifles.
