Delta Ultralight Sound Moderators

Roedale Delta Ultralight Sound Moderators where specialy developed in conjunction with the University of Applied Science – Osnabrück Germany, to be the lightest full bore capable hunting use sound moderator in the world.
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.
Delta ultralight
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 S4 Ultralight is, as far as we are aware, the lightest full bore capable sound moderator available anywhere in the world.
Sufficient peak noise reduction ( compliant with EU Regulation 10/2003 Art.3 & Art, 5) is achieved with the Delta S4 up to caliber.308Win or similar. The modularity of the unit makes it upgradable and adaptable for increased noise reduction or for larger calibers.
Roedale "Delta-Ultralight-Moderators“ provide an excellent combination of sound reduction, muzzle flash elimination and recoil reduction in a light, compact and robust package. This offers our Customers excellent performance and value for money.

Roedale Delta Ultralight Moderators are one of our most popular models and offer the following advantages:

  • Weight: from 175 g
  • Diameter: 39.7 mm (1.56“)
  • Length: from 147 mm (5.75“) long
  • Modular construction
  • Efficiency: 22.3 – 31.6 dB reduction depending on the caliber, baffle bore size and quantity of baffles
  • Attractive price: from 300.00€

Roedale Ultralight Moderators are designed for hunting or for pest control use. They are to be employed as a hearing protection device for the protection of the human hearing, animal hearing and environment against shooting noise damage and pollution.

Delta Ultralight Moderators are muzzle mounted onto a thread and are available to suit most common muzzle thread types and sizes:
Standard are: 1/2 "x20 UNF, M14x1, M15x1, M14x1 Spigoted, M15x1 Spigoted, 5 / 8x18,
5 / 8x24, M17x1, M17x1 Spigoted, M18x1
The following threads are also possible: 1 / 2x28 UNEF, M13x1, as well as other special threads on order.
Roedale Delta Ultralight Moderators offer excellent performance and are the lightest and most compact full bore silencer on the market. There are moderators which achieve greater noise reduction (e.g. Delta Pro X), but more sound reduction means more weight and larger dimensions. Gram for gram is the Delta Ultralight a highly recommendable sound moderator for hunting and pest control applications and offers excellent value for money.
