Our take:  Prometheus,by LayLax, is the manufacturer of some of the best Airsoft upgrade parts in the world.  Every Prometheus part is designed for high performance, durability even in the most extreme operating conditions,and quality you can see and feel.

Specifications:
- Works with most-all metal gearbox AEGs with any version gearbox (with the exception of the Marui PSG-1 sniper)
- We recommend the use of metal bushings, a Systema Polycarb Piston, and a Duracon Piston Head in your gearbox when using this high performance spring to maximize performance/gearbox durability
- 350-400+ FPS of power with correct installation and other gearbox parts capable of handling an M120

Disclaimer:  Any and all airsoft upgrade parts purchased from Airsoft Megastore will be used/installed at owner's discretion. Actual performance results depend on quality of installation, airsoft AEG barrel length, tightness of the air nozzle seal, and other possible performance-affecting factors.  We are not responsible for any damage that may occur with improper installation.  For best results, please do all upgrades at a certified professional airsoft technician/shop.
