Fixation in the center of the barrel

Improves indicators of accuracy, accuracy and stability of the balloon flight.
Barrel oscillation affects the spread and stability of the balloon flight.
The further the distance, the worse the accuracy and the higher the spread.
The insert can be integrated into almost any muffler, preferably towards the end of the barrel as shown in the photo.
Such a trifle as the centering insert can give a significant increase in the accuracy and stability of shooting, even on a basic barrel.
