Hop-up bucking engineered to improve shot-to-shot consistency and trajectory predictability on VSR-style and GBB platforms. A slightly tighter entry increases BB sealing for steadier muzzle energy, while the integrated C-Clip stiffens the lip to enhance seal effectiveness. The part is made from a newer silicone formulation—more elastic than classic rubbers—designed to balance BB backspin and long-range stability.
