KSC-MP9 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.

Because the inner barrel is too short and the air cushion effect is not obvious, inner barrels below 220mm have no air cushion groove design.

Note: Not compatible with the original inner barrel, as it is a proprietary specification.
