NexxSpeed CNC 7075 Aluminum Hop-Up Chamber (TDC Style) for KJWorks Shadow 2 / CZ-75 GBB Pistols

If you run a KJWorks Shadow 2 or CZ-75 and you’re chasing more consistent shots (and fewer “why did it do that?” moments), this NexxSpeed CNC hop-up chamber is a legit internal upgrade. It’s precision-machined from 7075 aluminum to tighten up fitment, reduce flex, and give the hop unit a more stable platform—exactly where consistency lives in a gas pistol.

The adjustment is step-by-step, so you can make small, repeatable changes instead of guessing where your hop setting was last time. NexxSpeed also uses a solid aluminum nub design to increase travel, giving you a wider usable adjustment range for dialing in different BB weights and setups.

Bottom line: if you’re upgrading your Shadow 2 / CZ-75 for better performance and durability, this is one of those parts that makes your tune feel more “locked in” once installed.
