CNC Hop-Up Chamber ALPHA AK AEG / HPA by Silent Industries
The CNC Hop-Up Chamber ALPHA AK by Silent Industries represents a revolutionary innovation for your airsoft gun. It is the most advanced chamber on the market, developed by a Slovak company specializing in innovative airsoft gun parts. This chamber introduces numerous cutting-edge features that are missing in competing models.
