So, brand new here. If I am posting in the wrong place, please move and/or tell me where to move it to.
I assembled this for a friend of mine who just got his first suppressor.
It works great in either configuration for semi-auto.
If you are using the binary mode it really needs the brace.
The short barrel (around 4 1/2 inch) keeps most standard rounds sub-sonic so no need for special ammo with the suppressor.
