The new Roedale "Hunter 55" moderator is a over barrel hybrid of the Delta SG12 and the Delta KK. The expansion chamber is stretched 75mm to the rear over the barrel and the overall length of the weapon is kept as short as possible. The expansion chamber is an integrated unit and does not seal on the rifles barrel, therefore flooded barrels are not a problem. The Roedale "Hunter 55" has ∅55mm in diameter and has a mono-core construction. This moderator is an absolute dB-destroyer and provides maximum noise reduction for hunters.
