nerf硬线管，将原作改为8线，并提供30度和40度两个可替换内芯（长度90.9mm，别问我为啥是这个长度）

请自行测试选择4线或8线，30度或40度内芯

实际测试78分左右使用40度内芯+4线，散布情况良好，降分3-4分左右

Nerf hard wire tube, changing the original to 8 wires, and providing two replaceable inner cores of 30 degrees and 40 degrees

Please test by yourself and choose 4 wires or 8 wires, 30 degree or 40 degree inner core

The actual test score is about 250 fps, using a 40-degree inner core + 4 wires, the dispersion is good, and the score is reduced by about 10-15 fps.
