Nielsen Sonic 40 Compact

Developed for .300 BlackOut

We have developed this suppressor for calibers with relatively small charges but still medium-sized projectiles. The result is a small and compact suppressor that works really well on smaller calibers up to .308 – Nielsen Sonic 40 compact is also available in a “max 9” size specifically for 9 mm parabellum. Now the surface is knurled.

The suppressor only goes 7 cm down over the pipe, and therefore has a smaller profile than e.g. a Nielsen Paradox 40, which is otherwise comparable in size.

The steel cores

As is known from the Sonic series, Paradox suppressors are also equipped with a steel core. The suppressor is therefore as solid and durable as possible. This core ensures that the suppressor can withstand the high temperatures that occur when firing many shots within a short period of time.

Caliber recommendation

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

The Sonic 40 Compact suppressor is specifically designed to be effective on the .300 AAC BlackOut caliber. However, the suppressor also applies to other smaller calibers.

Warranty

Warranty is according to local rules and is assumed by the dealer or distributor from whom it has been purchased. For any products purchased directly from us, we offer a 2-year warranty as described in our Terms & Conditions.

In Denmark we offer a full 5-year warranty, provided customers come to our manufacturing address with both rifle, ammunition and suppressor.

Maintenance

- - Avoid shooting the barrel too hot. Give the suppressor a light spray of WD40 or equivalent in the back end prior to mounting and after dismounting the suppressor. Particularly in humid weather.
  - Always allow the suppressor to dry-out thoroughly before placing it in storage.
  - Clean the suppressor as needed. Use only oil and cloth. A trip to the shooting range where the suppressor is shot medium heat is a good way to clear any excess gunpowder residue and soot.
  - Avoid the use of chemically basic cleaning agents, ultrasonic cleaners and brushes or scrubbing creams.
  - If the suppressor is to remain separable, it is recommended to regularly disassemble the suppressor and re-apply grease to the threads of the individual modules. Otherwise, modules will start to lock together over time. For our Sonic suppressors, this is not so much a problem due to the use of C-spanners. For all other suppressor, we offer a set of strap wrenches to aid in disassembly.
