Thank you for viewing. This appears to be an old barrel, but I can't remember the name or manufacturer, and it has just been stored for a long time. There is some metallic texture on the surface, but the feel hasn't changed. Weight: 22g per barrel (including point) Shape: Straight Maximum Diameter: 6.6mm Total Length: 50mm Point Exposure: 25mm The center of gravity is where the point is pointing in the photo. When setting the flight, it's around the second ring cut from the back, which is thicker. Please feel free to consider it. ♬
