Maxx Hopup Chamber Soft Flat Nub (4mm) for EVO-3

Enhance the performance and consistency of your EVO-3 setup with the Maxx Hopup Chamber Soft Flat Nub (4mm) for EVO-3 — a precision-engineered hop-up upgrade designed to deliver improved BB contact, stable backspin, and tighter shot grouping. Manufactured from a premium soft compound material, this nub provides smooth and even pressure distribution across the hop-up bucking for reliable and consistent performance. The 4mm flat nub profile creates a larger contact patch with the BB, helping improve hop consistency and overall accuracy while supporting a wide range of BB weights. Its soft construction allows better conformity to the bucking surface, reducing uneven pressure and promoting smoother spin application.
