There are outer barrels that have threading right in front of the front site just like in that picture.. I have one on my rifle, really makes my setup unique because I change inner barrels and just stick a short silencer on the front. Then add the barrel back on for longer range at will.
Draw aggressively, shoot decisively, holster reluctantly.
