Geissele AR-308 Reaction Rod (.308 / 7.62 NATO)

Description

The Geissele AR-308 Reaction Rod is a dedicated gunsmithing tool for AR-10/SR25 platforms designed to secure the barrel extension so torque is applied directly to the barrel extension rather than the receiver. It is intended for use in a bench vise in either horizontal or vertical orientation to assist with removal and installation of barrels, flash hiders, gas blocks and handguards. The rod’s integral splines engage the barrel extension to prevent rotation during torquing operations. Its design reduces receiver marring and removes the need to remove sights and mounts from a receiver’s M1913 rail during service.
