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.

Caliber recommendation

When choosing your muffler, it is important that you choose a muffler that fits the caliber you are using. On the graphic you can see which calibers can be shot through the muffler, as well as how well the amount of gunpowder can be handled by the muffler.

Since the Ghost models can be used on several calibers, it is therefore important to choose the Ghost model that is adapted to the largest caliber you want to use.

Never shoot the pipe too hot. Feel free to give the muffler a puff WD40 or similar at the rear end before mounting and after disassembly. Especially if the muffler is used in humid weather.
Always allow the muffler to dry before placing it in storage.
Clean the muffler as needed, using only oil and a cloth.
Avoid using alkaline cleaners, ultrasonic cleaners or brush and scrub cream.
If it is to remain possible to separate the muffler, it is recommended that you regularly separate all modules and apply a little new thread lubrication.
