For optimal performance, installation by users with basic DIY experience or a professional airsoft technician is recommended.

Product Notes

※ Notice: SW 98K and S&T 98K are different versions with non-compatible specifications. Please confirm your model before placing an order. This product is not compatible with the VSR-10 system.

※If the model cannot be fully charged, it indicates that there are no BBs in the magazine. Do not force the charging handle, as this may crush a BB in the hop-up chamber.
