Silent Industries Alpha CNC AK Hop-up Chamber

The Silent Industries AK Alpha Hop-Up Chamber sets a new benchmark in hop-up technology for AK platforms. Designed with uncompromising attention to performance and adjustability, it's a must-have for serious AEG and HPA builds alike.

 TRUE-TDC System – Precision Above All

At the heart of the Alpha chamber lies the TRUE-TDC (Top Dead Center) system, ensuring a perfectly vertical nub movement with no tilting or uneven pressure. This translates into exceptional hop consistency and the ability to easily lift heavy BBs (0.28g and up) with precision.

The included TDC trolley works with a variety of nubs (optimized for Silent Industries Black/Blue/Pink Nubs and ML Omega). A Blue Extended Nub is included for instant upgrade performance.

 Customization Without Compromise

• Adjustable Feed Tube – fine-tune the feed length to fit your magazines perfectly and reduce vertical play in the magwell

• Tensioner Ring System – two bucking lip tension rings (Black = tight, White = soft) let you control BB loading resistance precisely

• Barrel Alignment Groove – ensures accurate inner barrel positioning, especially useful with lower-end barrels

• Nozzle length adjustment with included shims – tailor fitment to your specific setup

 Optimized for HPA Builds

HPA engines like Wolverine, PolarStar, Gate Pulsar, or Sparklabs WOLF can exert excessive loading force, often leading to misfeeds or double-feeding. Thanks to the bucking lip tensioner system, the Alpha chamber helps solve these issues by letting you fine-tune loading resistance for flawless feeding.
