Предлагаю поделиться опытом и мнениями по стволику для болтовки
имеем гарантированный выхлоп 200 м/с при любом диаметре стволика.
рассматриваются стволики PDI :
1) High quality inner barrel
Its inner diameter is 6.08mm.
This is new concept.Made of Stainless steel.
It's not so tight, This barrel keeps libration after trigger release low, and it rise up accuracy.
The tolerance is ±0.002mm
05 inner barrels are producted by using the Cold hammering
(This tolerance is the highest quality in our industry).
But it's impossible to product the internal diameter 6.01mm.We needed more accuracy.
So we reaquired more precise scale.
2) Internal diameter is 6.05mm.
Made of Stainless steel.
Intenal diameter is 6.05 mm. It is more tight than normal inner barrel.
PDI inner barrel is "High Quality".
The tolerance is ±0.002mm
05 inner barrels are producted by using the Cold hammering.
The tolerance is ±0.002mm.Other barrel's tolerance is ±0.02 - 0.04mm.1/1000mm tolerance It is PDI only.
(This tolerance is the highest quality in our industry).
3) Internal diameter is 6.01mm.
Made of Stainless steel.We could product 01-inner barrel by using new technology of 05-inner barrel.
The tolerance is ±0.002mm
05 inner barrels are producted by using the Cold hammering(This tolerance is the highest quality in our industry).
But it's impossible to product the internal diameter 6.01mm.We needed more accuracy.
So we reaquired more precise scale.
Pro series
01 barrel is pro model,not 05 barrel.If they have extreme precision diameter,they may affect from
using which BB, situation, maintenance & other facters.Please be careful.
и длинна стволика
- 509 мм
- 554 мм
- 595 мм
Вычитал что для шаров 0,4 г оптимальная длинна стволика от 500 до 590 мм.
08 barrel has a larger bore than any other tight barrel,so less pressure & ball speed is not high.
But 08 Barrel has a stable air flow as below.BB will get the air stream,so it makes more fly & straight ballistic.
