ALPHA hop-up chamber by Silent Industries is designed for players who want to get the most out of their AEG or HPA platform. Compared to standard chambers, it offers a true TDC adjustment, precise barrel alignment, and advanced tuning options. Thanks to Gen2 upgrades such as the octagon design for better fit in the receiver, a 540° TDC dial for finer adjustment, and a POM CNC C-clip for stronger inner barrel retention, you gain even higher consistency and muzzle velocity stability. In practice, this means tighter grouping, more stable FPS, and reliable feeding even with heavy BBs or HPA systems. Every setup is unique, but we have found the combination with a 21.2 mm nozzle and heavier BBs from 0.28 g and above to work very well (depending on muzzle velocity).
