Machined from solid 7075 aluminium billet, The MagnusPro 2011 Hop-Up chamber uses a true vertical TDC (Top-Dead-Center) movement. Which means, regardless of your hop-up setting, the pressure point remains in the same position for consistent results.

Featuring over 4 patented designs, the Magnus 2011 unlocks your GBB pistol’s potential with adjustable pitch & yaw for perfect barrel alignment. The side and frame take up screws remove all excess tolerance between the hop chamber to achieve rock-solid mounting. Special barrel fixture blocks hold in the inner barrel in place without exerting uneven force, preventing misalignment and damage to the inner barrel.

Unique camshaft design allows you to make hop-up adjustments without the need for disassembly. Simply lock open the slide and adjustments can be made through the ejection port. Upon disassembly, a lockdown mechanism can be used to adjust the resistance of your hop-up adjustment or lock it down completely.
