A friend of mine in another state bought a 5.56 suppressor and it turns out that he is wanting to use it on a Tavor.

I don't know anything about the inner workings of that kind of firearm so I can't help him to tune the suppressed gun in. A long time ago I was telling him how I use heavier buffers or whatever on my ARs.

I am assuming there is some sort of buffer system but any insight into that platform would help.
