The AR10/SR25 Reaction Rod makes the removal and installation of barrels, flash hiders, gas blocks and hand guards much easier and simpler. 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 rods 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...

The AR15/M4 Reaction Rod makes the removal and installation of barrels, flash hiders, gas blocks and hand guards much easier and simpler.

The Super Reaction Rod was designed with the advanced armorer in mind, an armorer who frequently works on AR15/M4 platforms with over torqued, seized or Loctited barrel nuts. The Super Reaction Rod 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...

The Geissele Reaction Block is designed to aid in the assembly of lower receivers. Once the armorer has installed the buffer tube, the lower receiver can then be slid into the Reaction Block at the 12, 3, 6 and 9 oclock positions. This allows the armorer to rotate the lower receiver by 90 increments in the block simply by loosening the provided nylon screws, removing the lower receiver and sliding it back in at its desired orientation. The Reaction Block provides an ultra-stable platform for...

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...

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.
