Centering insert for silencer or outer barrel with outer diameter 24 mm and inner diameter 8,5 mm for inner head. The height is 13 mm. The insert is inserted into the silencer and the inner head is pushed through the hole. Due to the cleverly thought-out helical design, the insert can be inserted without any problem, but does not move freely. Immediately the inner head is inserted, the outer dimension stretches and thus "locks" the insert in place.
