S&T Kar98K Retrofit Kit

Installation Notes

Due to dimensional variations and manufacturing tolerances among different brands, minor fitting adjustments or modifications may be required when installing T-N.T. upgrade kits. For optimal performance, installation by users with basic DIY experience or a professional airsoft technician is recommended.

Product Notes

This product requires a T-N.T. dedicated bucking and is compatible with MARUI GBB inner barrels.

It is recommended to apply a little screw glue before tightening the screws, and please don’t tighten them too much to avoid deformation of the inner wall.

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.

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.
