The 16-inch, hammer-forged barrel is chrome lined and features a 1:9-inch twist. The end of the barrel terminates in a bird cage-style flash hider. Unlike the A2-style flash hider, this one is not closed on the bottom and could potentially cause problems for the shooter firing from the prone position over loose dirt or sand. Fortunately, Ruger uses a standard thread, ½-28, and the flash hider is removable. Those wanting to use a more suppressor friendly flash hider will easily be able to switch out this part.
