Delta Ultralight Magnum Modular Sound Moderators from Roedale Precision are high performance moderators and were specially developed in conjunction with Laboratory of Fluid Mechanics & Fluid Machinery at the University of Applied Science – Osnabrück, Germany, to be the lightest full bore capable hunting /sports sound moderator in the world.

The Delta Ultralight S4 is, to our knowledge, the lightest full bore capable sound moderator available. It provides more than adequate noise reduction and hearing protection for calibers up to .308win with only a weight of 175g to 195g.
Available in 3 diameter sizes of 40mm , 45mm and 50mm The Delta Ultralight Magnum Ø40mm and Ø45mm are designed for use with caliber .222 to 9.3x62. The Delta Ultralight Magnum Ø50mm is designed for use with 7mm to .458. All Ultralight models are caliber specific.
All parts of the Delta Ultralight Magnum are manufactured from the highest quality materials on CNC machines. The Ultralight is modular in design and all parts are available as an accessory, giving shooters the ability to tailor the moderator to their exact requirements.

We manufacture 2 types of baffles for the Ultralight; S type - standard (length 20mm – approx. weight 27g) and K type – short (length 10mm – approx. weight 20g). It is possible to fit a combination of baffles together to form a baffle stack. All parts can also be cost effectively replaced if need be.
