Mancraft CNC Airsoft Gearbox V2 QSC - 8mm

Mancraft CNC Airsoft Gearbox V2 QSC (8mm) is a premium, precision-built replacement shell for V2 AEG builds - ideal if you're upgrading a tired stock gearbox or putting together a high-performance custom setup. CNC machined for strength and alignment, it's designed to give you a solid foundation for reliable cycling, cleaner shimming, and easier maintenance, with the added bonus of QSC (Quick Spring Change)for fast power adjustments.

What it is

• A CNC machined Version 2 gearbox shell
• QSC / Quick Spring Change design for easier spring swaps
• 8mm bearing/bushing compatible (depending on your build preference)

Why it's a great upgrade

• Stronger base for demanding builds: CNC construction helps handle higher stress setups better than many cast shells
• Better alignment potential: A well-machined shell can make shimming and overall drivetrain smoothness easier to achieve
• Quick spring changes: Handy for adjusting to different site limits without a full teardown
• Perfect for rebuilds: Great option when a stock shell is cracked, worn, or you're chasing improved reliability

Key features

• CNC machined construction for durability and precision
• V2 compatibility (ideal for many M4/AR-style AEG platforms that use a standard V2 layout)
• QSC system for faster spring access
• 8mm support for common upgraded gear/bearing setups

Ideal for

• Techs and builders assembling a custom V2 gearbox
• Players upgrading to a more robust shell for higher-torque or higher-speed builds
• Anyone repairing a V2 AEG and wanting a long-term, stronger foundation

Notes before you buy

• Compatibility can vary between brands due to tolerances (receiver fitment, selector plate alignment, etc.)
• This is a gearbox shell, so you'll need your internal parts (gears, compression parts, trigger unit, etc.) to complete the build
• If you want, tell me the replica it's going into and whether you're building for snappy semi, high ROF, or maximum reliability - and I'll tailor the copy to match that use case.
