Domination by design
Most HPA adapters are simple — a functional conversion that gets the job done, but never really feels right. The MCO 08 GEN 2 was designed to fix that. Built from the ground up with real player feedback, it fits most popular replicas and comes with an (optional) Ultra Light Magazine that keeps the total weight just over 200g. Light enough to move fast. Solid enough to trust.
The hose inlet is where the MCO 08 immediately stands out. Instead of the typical central top-mount that gets in the way regardless of your dominant hand, the MCO 08 offers separate left- and right-handed asymmetric inlet options — your hose routes cleanly, your movement stays natural, and you stop fighting your own kit.
The 65° angled magwell isn't just for looks — it genuinely changes how the gun sits in your hand. Better balance, less wrist fatigue, and faster target acquisition all come from that single design choice.
Key Features
- Asymmetric Hose Inlet — Available in left- and right-handed configurations to keep your hose out of the way where it counts
- Dual Mag-Catches — Supports both standard reloads and CQB-style mag-bump changes, so you can reload the way you play
- Skeletonized Adapter Body — Weight is cut where it doesn't need to be, so you keep it where it does
- 65° Angled Magwell — Improves balance, natural aim, and overall responsiveness
- Single-Pin BB Nozzle Fieldstrip — Fast, tool-free disassembly for quick cleaning and maintenance
- BB Retainer — Keeps BBs in place during mag swaps so you're not picking them off the floor

A Few Things to Know
