Recommended for increasing initial speed measures for DSG PTW and short-length PTW .
HD6.00 inner barrel for PTW (inner diameter 6.00mm)

It is becoming popular these days tomake the gun length shorter than CQB. Also, those who combine with DSF (butterfly sector gear) to get that trigger feeling.

When the DSG is assembled, there are only 9 blade on each side of the sector. Although it may improve the sharpness itself, you will need an aditional inner barrel length or spring tension to obtain the proper initial speed.

If you make the inner barrel longer, the outer barrel will naturally be longer, which will affect the shape of the entire gun.
In other words, it will limit the exterior form.

There are limits to the number of spirals and the total length = free length of the spring.
Also when the spring tension is increased, the firing sound becomes larger which may not be suitable for ambush.


Therefore, we have tested with an internal diameter 6.00mm super power barrel PTW which is produced by our company.
Here are the following results. (average value of 10 measurements)

Although there is no large lift such as 10m / s, it's intial speed went up to 5-7m / s . There are slight variations in the outer barrel and chamber packing used, and it also varies depending on the inner diameter tolerance of the systema inner barrel.
The systema inner barrel used in the test is the inner barrel attached to the 2012 model.

As described at the beginning, if the PTW is set with a gear with a small number of blades in the sector, it may limit the external form ad spring tension.
