Thank you every one for the help. What I mean with "permanent attach" is that I'm not looking for a "very easy" or "super fast" remove or
Install. I said this because in my research i found too many products that the marketing is "super easy and fast" removal or install and for me the most important think is "the most silence possible" Im not looking for something fancy or extra mega good materials, Im looking for something simple but that trap the maximum sound possible because I saw some videos on YouTube that the sound of an AR with suppresor is like the same sound of a 9mm. Is my first time with this and I don't want to be frustrated when my AR sound a liiitle bit less after spend some hundreds.
The model that I said is a model that have good reviews online and if I remember good stop 28db of sound
