If the additional device is a sight, for example, the point of impact changes little or not at all when the barrel is shot hot.
  • the longitudinally movable floating bearing compensates for any axial displacements to the fixed bearing.

Since the floating bearing guides the adapter transversely but longitudinally on the housing, alignment that is unaffected by different thermal expansion coefficients of the housing parts (and / or of the tube) and the optics carrier or the adapter is ensured. Overall, the movable guide on the floating bearing on the housing ensures good shot precision even in continuous fire and when the pipe is hot-shot.
