Multi-caliber muffler for anything from .17 to .375
A Nielsen Sonic Ghost muffler comes with four different colored inserts: Red (max 6), Yellow (max 7), Green (max 8), and Blue (max 9.5). Each insert has different inner diameters which fit with resp. 6mm, 7mm, 8mm and 9.5mm calibers. Inserts for .17, .30 and 8.5 mm calibers can be purchased.
By unscrewing the lid of the damper, you can easily change the insert and thus use the damper on several pipes / rifles. This requires only one muffler for many calibers.
Low weight
To keep the weight to a minimum, almost the entire muffler is made of pure aluminum, which means that despite its large volume, it has a low weight. However, the inner tube – the part where the thread that is screwed on the pipe is – is still made of steel.
NOTE: as the inserts are made of aluminum, the muffler must cool down after 10 – 20 shots.
