The SHS Hop-Up Chamber V2 for M4/M16 replicas brings immediate improvement in trajectory control, ensuring compatibility and stability even under heavy use. Crafted in reinforced ABS, this New Ver.2 unit is designed to provide easy adjustment, secure bucking seating, and enhanced reliability in both precision and magazine compatibility.

Key features

Reinforced ABS construction: withstands repeated stress and prolonged use while maintaining functional integrity.

Optimized V2 rotary design: allows smooth and stable rear adjustment for quick, precise tuning.

Standard Marui compatibility for M4/M16 series: integrates without complex structural modifications.

Includes Hop-Up bucking and barrel stop: essential parts pre-installed for fast setup and optimal seal.

Adjustment stability: once set, holds position reliably even during intensive gameplay.

User benefits
Installing this Hop-Up chamber offers finer backspin control for BBs, resulting in more consistent trajectories and optimized range. The reinforced ABS reduces deformation risk over time, while the V2 rotary system enables rapid tweaks even in the field, minimizing downtime and enhancing overall performance.

Warnings and usage information (compliant with Italian GPSR regulations)

Keep out of reach of children: contains small parts that may pose ingestion or choking hazards.

Store in a dry place, away from heat sources or excessive humidity, to preserve ABS integrity.

Before any intervention, ensure the battery is disconnected and no power source is attached; work with the gearbox/energy source fully de-energized.

Follow disassembly and assembly procedures indicated by the replica manufacturer or certified technical manuals; use appropriate tools and avoid forcing the component beyond designed limits.

Use a compatible quality Hop-Up bucking and only recommended lubricants; avoid unsuitable products that could alter grip or cause abnormal wear.

It is forbidden to tamper with or alter the original geometry of the Hop-Up chamber: modifications may compromise safety, reliability, and precision, risking malfunctions or breakages.

After installation, perform dry tests (without BBs) to verify proper bucking seating, alignment, and absence of abnormal noises or jams; proceed to field use only if operation is regular.

Disassemble only with proper tools and following technical guidelines from the replica’s manual or certified instructions; if in doubt, consult an experienced technician.

Carefully store any spare parts provided (bucking, barrel stop) for future maintenance.

Perform all cleaning and maintenance operations only when the replica is fully de-energized: remove batteries and magazine before any work.
