안녕하세요！First of all sorry for the belated reply, and thank you for your message and interest in our products.

Our new upgrade / custom items for Tokyo Marui AKM GBBR was originally scheduled to be available in late Feb / early Mar. But due to unexpected logistic and Customs clearance issues in Taiwan (where our product lines are located), we regret that the items will be postponed to late Mar / early April. We are sorry for the prolonged waiting time and inconvenience caused.

The AK Magwell, Tactical Selectors, Front Sight Block, Enhanced Recoil Spring and Dummy Piston (Recoil Kit) have arrived HK and are awaiting Customs clearance. And the Threaded Outer Barrels, M-LOK Handguards, Stock Tube shall arrive next. Please stay tuned with us for updates.

Hope the above information helps. Again thank you very much for your understanding and support. 감사합니다！저희를 많이 지켜봐 주세요.

Best regards,

Hephaestus Airsoft
