Crafted from a solid 7075 aluminum billet, the MagnusPro 2011 Hop-Up Chamber features a true vertical Top-Dead-Center (TDC) movement. This ensures the pressure point remains consistent regardless of your hop-up setting, delivering reliable performance every time. With over four patented designs, the MagnusPro 2011 unlocks your GBB pistol's full potential. It offers adjustable pitch and yaw for perfect barrel alignment. Side and frame locking screws eliminate all excess tolerance between the hop chamber and the frame, providing a rock-solid mount. Specialized barrel fixture blocks secure the inner barrel without applying uneven force, preventing misalignment and damage. Its unique cam shaft design allows for hop-up adjustments without disassembly. Simply lock the slide open and make adjustments directly through the ejection port. When disassembled, a lockdown mechanism lets you fine-tune the resistance of the hop-up adjustment or lock it down completely for fixed settings.
