This Nielsen Sonic 45 .223 is a secondhand moderator threaded in 15×1.
The Nielsen Sonic 45 muffler 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 muffler. In addition, there are notches for hook wrenches on the muffler, so that it is easy to disassemble even after several hundred shots.
The steel cores:
The inside of the muffler is steel, encapsulated in aluminum. This gives us the strength and durability against wear and tear, 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.
