Our original silencer – a true all-round model
This silencer has a shorter rear end, one our standard Sonic 45. Since a Sonic 45 compact only covers 7 cm of the barrel, it can be used on rifles where there is a relatively short free barrel, such as. on semi-automatic or heavily shortened rifles. The muffler has a volume that can be used by a wide range of calibers. On smaller calibers, our other, smaller silencers can do the job, but in principle, this muffler can cover almost any caliber from .243 to .375

Our Nielsen Sonic 45 silencer has a good and solid construction, which allows it to be used even on calibers where the amount of gunpowder exceeds what can be in the silencer. In addition, there are notches for hook wrenches on the muffler, so that it is easy to disassemble even after several hundred shots.

Steel core
The inside of the silencer is steel, encapsulated in aluminum. This gives us the strength and durability against wear, while the weight can be kept down. This is why we dare to give a 5 year total warranty for all mufflers purchased directly from us.

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.

The Sonic 45 muffler is a true all-round muffler. Its volume and wall thickness make it suitable for a wide range of calibers.

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. A ride on the shooting range where the muffler is shot moderately hot will also clean it of excess soot.
Avoid using alkaline cleansers, ultrasonic cleaners or brush and scrub creams.
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.
