Thanks Russ Hudson's comments,I added a thicker bigger pump base, but also lengthen the pump
In addition to lengthening pump,also increase the distance between the two pump will be available as 16 darts horder.
1.空氣空間少/高壓力/長槍管/100度
2.空氣空間少/高壓力/長槍管/150度
3.空氣空間少/高壓力/短槍管/100度
4.空氣空間少/高壓力/短槍管/150度
5.空氣空間多/大量空氣/長槍管/150度
6.空氣空間多/大量空氣/長槍管/100度
7.空氣空間多/大量空氣/短槍管/100度
8.空氣空間多/大量空氣/短槍管/150度
Rifling will increase from the original four to six,
In order to enhance greater accuracy, we tested eight combinations:
1. Small air space/high pressure / long barrel / 100 degrees
2. Small air space/high pressure / long barrel / 150 degrees
3. Small air space/high pressure / short barrel / 100 degrees
4. Small air space /high pressure / short barrel / 150 degrees
5. Large air space /large amount of air / long barrel / 150 degrees
6. Large air space /large amount of air / long barrel / 100 degrees
7. Large air space /large amount of air / short barrel / 100 degrees
8. Large air space /large amount of air/ short barrel / 150 degrees
After testing, short barrel coupled with a large air more stable, and finally decided to increase air tank, this is a big modification.
Because of the large cylinder on the shoulders of a lot of height increase, part of the buttstock a little is not enough, so add a mini-buttstck.
Compare it! what is the difference?
