Geissele Reaction Rod (5.56/.223) Description

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.

The Geissele Reaction Rod (5.56/.223) is machined at Geissele Automatics’ state of the art manufacturing facility in North Wales, Pennsylvania. The rod is cut from a solid bar of 4140 Chrome Moly steel, properly quenched/tempered and ground to an exact diameter that is smooth and straight so the rod will enter an upper receiver without wobble.

The Reaction Rod is designed to be gripped in a bench vise so that the rod is either horizontal or vertical. The upper receiver is then slid onto the rod and the rod’s integral splines enter the barrel extension and secure the barrel extension from turning. This allows all the torque from barrel nut wrenches to go directly into the barrel extension. In contrast, receiver vise blocks transmit the turning force into the aluminum receiver, a good part of which passes through the small, easily distorted receiver index pin. With the Geissele Reaction Rod, marring of an upper receiver’s finish by gripping and twisting inside vise blocks is eliminated and so is the need to remove sights and mounts from the receiver’s M1913 rail.

 

Gas Block Pin Punch Set Description

The Geissele Gas Block Pin Punch Set is made specifically for the removal and installation of the 0.078" roll pin that secures the gas tube to the gas block of an AR-15/AR-10. Removal of a rusted-in gas block roll pin has always been a challenge since there are no commercial pin punches in 0.078" diameter. Additionally, 1/16" (0.062") punches have a tendency to bend and very few starter punches are available in 1/16" diameter. 

The Geissele Gas Block Pin Punch Set makes gas block work a whole lot easier. The first punch to grab when removing the roll pin is the Starter Punch. This is the punch with the long, tapered end. The long taper is much more resistant to bending and buckling than the straight shank of the Pin Punch. Use the Starter Punch to get the roll pin moving. Then, use the Pin Punch to drive the roll pin out completely. The Geissele Gas Block Pin Punch Set is  made from properly hardened and tempered 01 tool steel. The Gas Block Pin Punch Set is considered a consumable item, meaning they will eventually wear out and will need to be replaced. Geissele will not replace tools damaged from misuse or normal wear and tear. Always make sure your weapon is unloaded and the magazine removed before starting work. 

 

Gas Block Roll Pin Tool Description

The hole in the tip of the Gas Block Roll Pin Tool is sized so that the roll pin will need to be pressed into the tool first (the roll pin will not just slide in). Stand the roll pin on a hard surface and tap the tool onto the pin to seat it in the tool. When the hole in the gas block grabs the roll pin, the pin will collapse enough so the tool can be removed from the roll pin. Afterwards, all that is needed is a tap with a punch to seat the roll pin in the gas block.

 

Trigger Fitting Pin Description

The Geissele Automatics Trigger Fitting Pin is designed to assist with trigger installations. The Fitting Pin is the same size as the trigger and hammer pins, allowing the Fitting Pin to help remove an existing trigger by being able to better press the pins out, or to act like a slave pin when installing a new trigger.

AR15/M4 Armorer's Package Notes

The Geissele Reaction Rod (5.56/.223) is compatible with the HK MR556 upper receiver.
