HOW TO MODIFIED KSC-MP9 GBB
​NOZZLE & PUTTER

Because the KSC MP9 GBB nozzle is shorter & putter above the groove is shallow, that may result in the following:
1. In the loading time nozzle can not be complete and indeed pushed BB to the correct position.
2. Because the putter above the groove is shallow of the restrictions, when loading the nozzle can not be fully pushed into the bucking, resulting in poor sealed.(muzzle speed down)

T-N.T. sharing of a simple adjust method to solve this small problem, do not need time-consuming dismantling nozzle can be simply completed!!

This method is to "increase the depth of the groove above the putter" to achieve the "when loading can make the nozzle can be pushed forward", the purpose to improve the BB loading position is not correct and poor air-sealed  problem.
(This method is for reference only, and recommended to have the DIY ability)

1. (Side view of the nozzle)
Please refer to the red arrow in the photo:
Left side for the original nozzle - putter groove is not polished.
The right side is the depth after polishing.

2. Only need to use a small file gently polished groove, about 1mm.
(Note that do not polish too much, may affect the strength of the putter part, resulting in loading and impact due to fracture!!)
