CNC Hop-Up chamber AK Alpha

Silent Industries' innovative Aplha CNC hop-up chamber with True TDC and a variety of other enhancements.

TRUE TDC SYSTEM

For the most consistent pressure on the bucking, TRUE-TDC system ensures perfectly vertical nub movement — no tilting, no uneven pressure.

The included TDC trolley is designed for use with various nubs, allowing you to customize your setup. We recommend Silent Industries Black Nubs, Blue Nubs, Pink Nubs or ML Omega, or other similar-height nubs, as the system is optimized for them.

With maximum travel distance, TDC system delivers exceptional hop performance, making it easy to lift heavy BBs with precision and consistency.

ADJUSTABLE FEED TUBE

The Adjustable Feed Tube allows you to set its length, ensuring an optimal fit for your magazines.

By fine-tuning the length, you can improve feeding consistency and minimize vertical movement within the magwell.

For users with magazines from different brands, test all of them first to find the best universal adjustment.

TENSIONER RING SYSTEM

Silent Industries revolutionary tensioner system is very easy to assemble, it uses Tensioner Rings. In the package you get two rings, black & white (additional rings are available for even more settings). We recommend trying ML SuperMacaron with White Ring.

Black is for tighter lip tension. White is looser lip tension.

BARREL ALIGNMENT GROOVE

The Alpha features a groove that can help you with barrel alignment, we recommend using this as a reference point as some less quality barrels can have misaligned hop-up window.

We recommend Sniper Upgrades, PDI, Lambda, ZCI, Prometheus, KM Head, T-NT stainless steel barrels.

GAME CHANGER FOR HPA BUILDS

HPA engines in general have much stronger BB loading force compared to AEGs, this sometimes can lead to issues such as double feeding, mid-cap syndrome or BB placement. The Alpha chamber with it’s innovative bucking lip tensioner system can help with these issues as you can fine tune the loading resistance.

It is a highly recommended chamber for Wolverine, PolarStar, Gate Pulsar, Sparklabs WOLF engine builds.
