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.
