Specna Arms ORION V2 gearbox shells - with bearings

Specna Arms ORION™ V2 gearbox shells with 8mm ball bearings. This highly durable gearbox is designed specifically for the Specna Arms EDGE™ series electric AR15 airsoft guns equipped with the Ver2 gearbox. The gearbox is equipped with the ESA™ Quick Spring Change System. Reinforcement filings are ready at the front of the gearbox. The reinforcement filings distribute the impact force of the piston more evenly across the entire front end area, thus improving the durability of the gearbox.
