T hop-up ALPHA for AK AEG and HPA series - Silent Industries

The ALPHA AK hop-up chamber from Silent Industries represents the pinnacle of technology for hop-up chambers intended for AK AEG and HPA airsoft replicas. Developed by a Slovak company specializing in innovative components, this chamber introduces revolutionary solutions to maximize precision, consistency, and reliability, solving problems where other chambers fail. Manufactured according to the TM standard for AK, it is compatible with E&L, Arcturus, Cyma, LCT models, including PP-19 Vityaz, VSS and AS VAL.

Main Innovative Features:

1. Real TDC Pressure (Top Down Centered): To achieve the most consistent pressure possible on the bucking, the ALPHA chamber uses TDC technology. The pressure arm moves only vertically (up/down) thanks to an included TDC carriage, designed to accommodate standard buckings (nub). This guarantees perfectly uniform pressure and offers the longest possible stroke, allowing you to easily lift even the heaviest BBs. (Silent Industries or Omega Maple Leaf nubs are recommended).
2. Revolutionary Ring System for Bucking Lip: This tensioning system uses tightening rings (two included: standard black, looser white; other optional) that fully support the hop-up bucking lip. This improves sealing and allows you to finely adjust the resistance during BB loading, solving common problems in HPA systems (double feeding, Mid-Cap Syndrome, etc.). (Use with ML Super Macaron or MrHop buckings is recommended).
3. Adjustable Chamber Nozzle: The chamber nozzle is adjustable, allowing you to adapt the length of the feeding ramp to the specific magazine in use. This improves BB feeding and reduces magazine wobble.
4. Barrel Alignment Groove: A groove helps in aligning the inner barrel (use as a reference). (High-quality barrels such as PDI, Lambda, Prometheus, etc. are recommended).
5. Optimization for HPA: The ring system for the bucking is particularly advantageous for HPA systems (Polarstar, Wolverine, GATE Pulsar), helping to solve problems related to high pressure on the BBs.
