Well noticeable without appreciable effect on the degree of attenuation. At the same time, the surface is glass-blown for less glare and the edges are rounded.

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

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 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.
