Hammerli Pneuma Elite Shroud mod
To reduce sound noise, I made the shroud from steel plate and blue steel wire rod.
Each steel plate was but as 30deg. oval shape with 6.9mm (mini.) diameter oval hole. In order to reduce higher tone sound, I picked steel and inside design is just like Edgun. Outside is 25mm dia. x 150mm length.

As same as many cutom makers, sound reduction device is DIY only due to the patent of sound reduction design. There are many law troubles since after WWII.
are you making these for the Pneuma? Or is it just a one-off for you? I also have the Elite 10.
