This CYMA replacement cylinder is specifically engineered for SR-25 Quick Buffer System (QBS) AEG rifles. SR-25 platforms utilize unique extended Version 2 gearbox configurations that require properly matched internal components for optimal performance.

The OEM-style design ensures strong compatibility with many CYMA SR-25 rifles and compatible QBS-style gearbox systems.

Ideal Applications

• SR-25 DMR builds

• CYMA SR-25 gearbox rebuilds

• High-FPS outdoor rifles

• Precision AEG tuning

• Compression restoration projects

• Custom designated marksman rifles

Its drop-in fitment minimizes installation hassle for experienced airsoft techs and upgrade enthusiasts.

Perfect for High-Performance Airsoft Upgrades

When building a precision SR-25 airsoft rifle, compression consistency becomes increasingly important. This non-ported cylinder pairs well with upgraded internal components to help maximize efficiency and performance.

Recommended Compatible Upgrades

• Reinforced piston assemblies

• CNC cylinder heads

• Air seal nozzles

• High torque motors

• MOSFET systems

• Tight bore inner barrels

• Heavyweight BB setups

• Enhanced hop-up buckings

A properly matched cylinder volume can significantly improve the efficiency of your airsoft rifle while maintaining consistent FPS readings during gameplay.
