Firearm Maintenance

The RTT™ is a DLC (Direct Laser Sintered) 3D printed stainless steel tool that allows the user to remove the rear takedown pin on an AR15 receiver without having to un-stake and remove the Castle Nut & End Plate.

The tool is inserted into the slot on the rear takdown and features a ramp that allows the detent to ride up and out of the channel onto the outer diameter of the pin.

The pin can then be removed and a Pivot Pin used to hold the detent back while a new pin is inserted.

Ideal for swapping out damaged or replacement pins.

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 act as either a punch to help remove an existing trigger, or to act as a slave pin when installing a new trigger.

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 o'clock 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 performing an array of lower receiver operations as well as making the installation of the buffer retainer nut quick and easy. This is all possible while keeping both hands of the armorer free to work, saving both time and frustration.

The AR15/M4 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 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.

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.

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 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.

The Geissele Suppressor Alignment Rod (SAR) is a precision gauge used to verify the alignment of a suppressor to the bore of a firearm barrel.

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.

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 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 in a 360° both vertically, and horizontally.
