Our “Max size” is the maximum size caliber that the muffler can be used for.

Too large max size in relation to caliber, will mean significantly reduced efficiency for the muffler.

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.

Sonic 55 is the largest muffler we produce. It is aimed at the largest calibers and for those who want the best possible attenuation. A Sonic 55 handles both .338 Lapua Magnum and .375 Chey Tac without any problems.

Due to the large volume of a Sonic 55, it is not produced for 6 mm calibers. For maximum attenuation on these calibers, we refer to the Nielsen Paradox 50 silencer.
