Geissele Automatics 10169 Reaction Rod Steel 223 Rem 5.56x45mm NATO AR15/M4/M16

The Geissele Reaction Rod (5.56/.223) makes the removal and installation of barrels, flash hiders, gas blocks and hand guards much easier and simpler. With the Geissele Reaction Rod, marring of an upper receivers finish by gripping and twisting inside vise blocks is eliminated and so is the need to remove sights and mounts from the receivers M1913 rail.
