Description
Daystate Blackwolf Barrel Tensioner
Available for 17, 23 and 28 inch barrel
The Daystate Blackwolf Barrel Tensioner improves barrel harmonics and, therefore, downrange accuracy. It is easy to fit and requires no special tools. Three versions are available – 17 inch, 23 inch and 28 inch. You must select the correct one to match your Blackwolf’s barrel length.
What does a barrel tensioner do?
Barrel harmonics are an important factor in a rifle’s accuracy. All barrels vibrate during the firing cycle, creating node and antinode points. Adjusting the wavelength of this vibration can have a dramatic effect on accuracy. This is because it dictates how well the projectile leaves the bore as its starts its journey to the target.
A barrel tensioner lets you adjust the tension of the rifle’s barrel. So this changes the frequency (or wavelength) at which the barrel vibrates during the firing cycle. Many target shooters swear by barrel tensioning devices.
Note: Some Blackwolf models come with a Barrel Tensioner already fitted. Currently, it is factory-fitted to:
- Blackwolf Grey Laminate (Cylinder and Bottle Type)
- Blackwolf Walnut (Cylinder and Bottle Type)
- Blackwolf TAC (Tactical)
However, the tensioner currently is not fitted to the standard Blackwolf model, identifiable by its sating carbon grey wood stock.
How to fit the Barrel Tensioner
Instructions are provided. But fitting a Barrel Tensioner to the Daystate Blackwolf PCP air rifle is easy! Simply unscrew the Blackwolf’s outer barrel shroud – a carbon-fiber tube – and slide it off from the muzzle end. This exposes the Blackwolf’s barrel. Remove the end nut.
Now, slide over the carbon-fiber barrel tensioner tube. Then refit and hand-tighten the nut at the muzzle end. The degree of accuracy gain will vary according to the actual tension of the tube. You should set the nut to a hand tightness of between 5 and 8Nm. This tension is based on findings from our own Accuracy Research Team (ART). However, you can experiment with your own torque settings. This will help fine-tune the barrel harmonics to match your rifle, barrel, pellet and power combination.
Once the Tensioner has been fitted in place, refit the outer carbon-fiber barrel shroud.
Important: You must not overtighten the tensioner tube – 8Nm maximum!!!
