Delta-KK Sound Moderators

Roedale Delta-KK Sound Moderators are designed for use on Rim Fire Firearms and are manufactured from the highest grade high strength aluminium alloy. Each part is manufactured from the highest grade high strength aluminium alloy used in the aerospace and defence industries. Parts are CNC machined from solid billets. The surfaces are hardened and coated with a hardcoat-anodizing finish to Mil-Spec type III matt black. This coating lends numerous functional qualities to aluminium components.
Wear-resistance and hardness: The high wear-resistance is based on the hardness and the morphology of the aluminium oxide coating. The attainable hardness of the layer lies between 400 and 500 HV0,025.
Heat conductivity: The heat conductivity amounts to from around 1/10 to 1/30 of the heat conductivity of the base material.
Temperature resistance: Hardcoat layers withstand brief temperature peaks to 2,200 K.
Impact Resistance: The impact resistance complies with ISO 2376 and amounts to 50 µ m: 1213V.
The aim of this coating procedure is functionality and not beauty. Minimum colour differences on the surface may occur between batches.
The Delta-KK achieves sufficient peak noise reduction ( compliant with EU Regulation 10/2003 Art.3 & Art, 5)with calibers such as .17HMR or .22LR and similar.

Roedale Delta-KK Moderators offer the following advantages:

  • Weight: from 140 g
  • Diameter: 39.7mm (1.56“)
  • Length: 95mm (3.74“) long
  • Modular Construction
  • 1/2x20 UNF Thread

Roedale Delta-KK Moderators offer excellent performance.
