What is up with the "pistols" such as the P516, P716, PM400, P556xi? It seems that they shoot rifle ammo (5.56 or 7.62) and in profile look like AR style SBRs but in the description I see that what appears to be a shoulder stock is actually a forearms brace. Seems a little inconvenient to me to...
I'm converting my 7.5" P516 to a SBR (I'll file the form 1)
