A premium, fully-licensed Umarex/VFC (GHK) replica that pairs authentic Gen-5 ergonomics with MOS optic-readiness and a realistic gas-blowback system.

Pros 

Pros: authentic handling and ergonomics; MOS ready for quick optic mounting; durable Cerakote finish; realistic blowback feel and quality internals (GHK/VFC pedigree). Considerations: gas performance is temperature-dependent (colder = lower FPS/less blowback); check your local site limits and RIF (real imitation firearm) requirements in the UK before sale/use; MOS adapter plates are sometimes sold separately. If you need UK-legal tuning ask your retailer to confirm joule/FPS on dispatch.
