It has a massive length of 185mm and 50mm wide and weighs only 155gr. I inside are three chambers that offer Great Sound Reduction. The 1/2-20 UNF threads are aluminum so you you can install and uninstall many times without having the threads getting damaged. This is a one-piece lightweight Construction and it’s covered with carbon vinyl for a nicer look. It can’t be opened. It will work with .22 .25 and .30cal
Tested and works better than the DonnyFL`s, much more Sound Reduction!
