Geissele AR15/M4 5.56/.223 Super Reaction Rod 15-193

Geissele's AR15/M4 5.56/.223 Super Reaction Rod allows armorers and gunsmiths to remove barrel nuts that are over torqued, Loctited, or seized. It works by pre-loading the barrel nut extension to the lugs of the Super Reaction Rod to eliminate any movement before adding torque to the barrel nut, while at the same time fixing the upper receiver into place. Having the barrel nut extension mated to the Super Reaction Rod lugs and fixing the upper receiver before torqueing will remove any potential stress that could be placed on the index pin. This allows the armorer to place tremendous torque on the barrel nut. The Super Reaction Rod's pre-loading system can also be removed to allow it to work just like a standard Reaction Rod, which allows upper work to be performed with 360 degree movement, both vertically, and horizontally.
