CNC Hop-up chamber ALPHA M4/16 AEG/HPA by Silent Industries introduces a revolutionary innovation for your airsoft gun, representing the most advanced chamber on the market developed by a Slovak company specializing in innovative parts for airsoft guns.

How does the ALPHA chamber surpass the competition?

1. Truly Functional TDC Pressure

To achieve the most consistent pressure on the bucking through the pressure arm, it was necessary to use TDC technology. This means that the pressure can only move up and down. The package includes a TDC trolley designed for nubs, so you can use your preferred type of nub.
We recommend using Silent Industries nubs or other high nubs (e.g., Omega Nub from Maple Leaf):

• 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 *

This TDC system provides the longest stroke, allowing you to easily lift heavy BBs.

2. Hop-up bucking ring system

The revolutionary tensioning system is easy to assemble and uses clamping rings. You will receive two rings in the package – black and white (for finer adjustments, additional rings can be purchased: tight and extra tight bucking rings). We recommend trying the ML Super Macaron or Mr. Hop bucking with the white ring for looser tension and the black ring for stronger tension.
This is the only chamber on the market that fully supports the hop-up bucking lip.

3. Adjustable chamber mouth to fit the magazine

The adjustable mouth allows for setting the feed ramp length of the chamber to the magazine, so you can fine-tune it according to your magazines. This improves BB feeding and reduces magazine movement in the well.

4. Barrel Alignment Groove

The Alpha chamber includes a groove that helps you with barrel alignment. We recommend using it as a reference point because some lower-quality barrels may have misaligned hop-up windows. We recommend high-quality stainless steel barrels from brands like PDI, Lambda, or Prometheus, KM Head, T-NT, ZCI.

5. Revolution for HPA Systems

HPA systems generally develop much higher pressure on BBs compared to AEGs, which can lead to issues such as double feeding, Mid-Cap syndrome, or BB alignment problems in the chamber. The Alpha chamber with the innovative hop-up bucking lip ring can help with these issues by allowing fine adjustment of resistance during loading.
We recommend using HPA systems from Polarstar, Wolverine, or GATE Pulsar.
