I was wondering if the Ruger AR-556 has a threaded barrel for a silencer or suppressor? And if not, how does one install it or do i have to go through a gunsmith?

Riley, yes the Ruger ar556 comes with a threaded barrel with 1/2×28 thread pitch. A gunsmith shouldn't be necessary because a suppressor just screws on and off. Any suppressor with a 1/2×28 threads that's rated for 5.56/223 will fit. Hope this helps.
