CNC Hop-up chamber ALPHA M4/16 AEG/HPA from Silent Industries is likely the most advanced hop-up chamber for airsoft weapons and offers a truly functional TDC pressure.
To achieve maximum consistent pressure on the rubber via the pressure arm, it was necessary to use TDC technology. This means that the pressure can only move up and down.
This TDC system provides the longest stroke, which means you can easily lift heavy BBs with it.

Silent Industries offers the following types of pressure Nubs:

  • black classic (85A, hard) - for barrels with a hop-up window diameter of 4-5mm and weapons with a power output of 2+J, suitable ammunition 0.32 - 0.40g *
  • black extended (85A, hard) - for barrels with a hop-up window diameter of 6-7mm and weapons with a power output of 2+J, suitable ammunition 0.40g and heavier *
  • blue classic (70A, soft) - for barrels with a hop-up window diameter of 4-5mm and weapons with a power output of up to 2J, suitable ammunition 0.28 - 0.32g *
  • blue extended (70A, soft) - for barrels with a hop-up window diameter of 6-7mm and weapons with a power output of up to 2J, suitable ammunition 0.30 - 0.36g *

* recommended BB weight is purely indicative and always depends on the specific assembly of parts
