Laylax Prometheus Elite CNC Hop-Up Chamber for M4/M16 AEG

When victory on the airsoft field depends on precision, consistent velocity, and maximum range, the Laylax Prometheus Elite CNC Hop-Up Chamber for M4/M16 AEG delivers uncompromising results. Engineered in Japan by industry-leading airsoft innovators, this chamber serves as a vital performance foundation for custom Version 2 M4 and M16 builds, eliminating the performance-robbing flaws inherent in standard factory hop-up units.

Precision Japanese CNC Machining

Crafted from a single block of aircraft-grade aluminum, this chamber eliminates structural flexing, warping, and premature wear. Standard plastic or cast chambers often flex during operation, leading to subtle compression leaks and erratic shot trajectories. The Prometheus Elite chamber maintains absolute structural rigidity under stress, providing a smooth, micro-polished feeding route that prevents BB jamming—even during high-CAP or high-rate-of-fire magazine dumps.

Superior Airseal and Velocity Stability

By holding tight mechanical tolerances around the gearbox nozzle interface, this chamber optimizes nozzle-to-bucking seating. This tight seal prevents pressurized air from escaping around the BB during discharge, directly translating to higher FPS stability, cleaner energy transfer, and significantly tighter shot groupings over long distances. Included barrel retention rings securely lock your inner barrel in place, preventing side-to-side vibration and twisting that cause frustrating fliers.

Tactile Rotary Pressure Tuning

The unit incorporates a modern rotary adjustment wheel that allows fine-grained, incremental control over hop-up nub pressure. Unlike traditional three-gear assemblies that loosen and drift due to motor vibration and recoil, this rotary mechanism utilizes a heavy-duty tension system that keeps your setting locked until you change it. Whether slinging heavyweight 0.28g BBs in CQB or heavy 0.32g+ rounds for outdoor DMR setups, dialing in flat trajectories is effortless and reliable.

Key Features & Technical Benefits:

• Aircraft-Grade CNC Aluminum: Guarantees absolute structural rigidity, zero flex, and lifelong durability.

• Rotary Dial Mechanism: Delivers smooth, repeatable backspin adjustment that resists unwinding under heavy fire.

• Optimized Airseal Geometry: Maximizes compression between nozzle, bucking, and inner barrel for stable FPS outputs.

• Precision Barrel Stabilization: Eliminates inner barrel play and side-to-side twist for improved grouping tightness.

• Universal V2 Compatibility: Engineered for seamless drop-in fitment across standard TM-spec M4/M16 AEG platforms.

Installation & Field Guidance

For optimal results, pair this chamber with a Prometheus EG precision inner barrel and a high-performance hop-up bucking. During installation, ensure the hop tension nub sits straight within the arm window before sliding the barrel assembly home. Apply a microscopic layer of pure silicone lubricant to the outer bucking sleeve to aid insertion into the aluminum body, ensuring no lubricant contacts the internal rubber friction patch.
