  • Socket wrench set for Nielsen Sonic 55


    Socket wrench set for easy disassembly of Sonic 55 mufflers. One key is used as a counterweight, and the other key to apply force. It is recommended to buy threaded pasta; a small amount of thread should be applied to the thread before reassembling the muffler.

  • Support bushing


    Fits all telescopic silencers we manufacture. For regular use the support bushing should be approx. 0,4 mm larger than the diameter of the barrel where the support bushing rests. When using a sling mount for Sonic 45 and Paradox 45 silencers, the support bushing should be a tighter fit, with only 0,1 – 0,2 mm air between barrel and support bushing.

    If in doubt, please simply select “14 mm” and write the diameter of your barrel at the appropriate distance from the muzzle (14 cm for Sonic 45/55, 10 cm for Paradox & Ghost, and 7 cm for Compact models) as a comment on check-out. Also include whether the silencer has a sling mount.

  • Thread protector


    Thread protectors to nearly all types of thread we manufacture our silencers with. You choose both the appropriate thread and the diameter of the thread protector when purchasing. Hereby the outer diameter of the thread protector can match that of the barrel.
