Wyhaq showcases the TTI CNC Aluminum TDC Hop-Up Chamber designed for the ASG CZ Shadow 2 gas blowback pistol. This video highlights a CNC machined aluminum hop-up chamber that replaces the traditional clamshell design. Unlike other chambers restricted to proprietary inner barrels, this model accommodates standard VSR10 and GBB barrels. Additional features include a set screw for barrel pin stabilization, a hop-up setting screw to prevent elevation shift, and integrated legs for enhanced inner barrel support.
