Delta-Pro Sound Moderators

Roedale Delta-Pro Sound Moderators are a further developement of the Delta Ultralight Moderator and use the same baffle type. A back over the barrel, contained blast chamber slightly increases the internal volume of the moderator when compared to the Delta Ultralight. By extending the blast chamber back over the barrel it is possible to reduce the increase in length caused by fitting a moderator to a rifle. Additional baffles can be added to increase the sound reduction capability if required.
Delta Pro
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-Pro S4 achieves sufficient peak noise reduction ( compliant with EU Regulation 10/2003 Art.3 & Art, 5)up to caliber.308 Win or similar. The modularity of the unit makes it upgradable and adaptable for increased noise reduction or for larger calibers.
Roedale "Delta-Pro 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-Pro Moderators offer the following advantages:

  • Weight: from 320 g
  • Diameter: 39.7 mm (1.56“) / 44.5mm (1.75“)
  • Length: from 200 mm (7.8“) long ( lengthening the rifle by only 100mm / 3.9“)
  • Modular construction
  • Efficiency: 22.3 – 31.6 dB reduction depending on the caliber, baffle bore size and quantity of baffles
  • Attractive price: from 360.00€

 

Roedale Delta-Pro 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.

Roedale Delta-Pro Moderators are back over the barrel mounted onto a muzzle thread and have a delrin bush threaded into the rear which is fitted to the barrel profile. (The expansion chamber is a contained unit consisting of a barrel sleeve and outer tube) They 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-Pro Moderators offer excellent performance and slightly increased noise reduction when compared to the Delta Ultralight.
Delta Pro rear ends are available as accessory parts enabling existing Delta Ultralight Moderators to be converted to back over barrel fitting. Gram for gram the Delta-Pro is a highly recommendable sound moderator for hunting and pest control applications and offers excellent value for money.
