Geissele

A comfortable and ergonomic SOPMOD stock from B5 Systems is mated to a 7075-T6 aluminum Mil-Spec six position buffer tube. A Geissele Super 42 braided wire buffer spring surrounds an H1 buffer so that even low powered steel case ammunition will cycle reliably. The reciprocating bolt carrier group is made by Geissele Automatics from Mil Spec 8620, 4140, 4130 and Carpenter 158 steel with the ID of the carrier and gas key hard chrome plated. All parts of the BCG are Manganese Phosphate coated...

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 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.

The Geissele 2 Stage (G2S) was designed to be a high quality, cost effective option of the SSA. The G2S is a 4.5lb. non-adjustable combat trigger that is a precision two-stage trigger and allows precise and accurate trigger control. The G2S is manufactured from the same tool steel as the SSA. Visually, from the outside of the weapon there is no difference from the SSA and the feel and reliability is the same. The G2S however has a different way of holding the hammer pin in place, there is no...

The Geissele Super 42 Spring was designed to improve the function and reliability of your AR-15 pattern rifle. Its unique spring design uses three independent strands of wire, just like the German MG42 Machine Gun. This concept acts as a harmonic damper and energy absorber by allowing the springs to flex separately from each other. This flex helps displace excess energy which decreases the chance of spring failure and assists with making your AR-15 more reliable.Compared to the stock spring,...

To change the Geissele Automatics H1 Buffer assembly to the heavier H2 or H3 buffer setup, you will need to disassemble and re-assemble the buffer replacing the steel weights with the correct number of tungsten weights. 1 Tungsten weight to add over all weight to your buffer setup. (H1 / H2 / H3 setups) Note : We are a factory direct LE/Mil dealer. Special Order turn-around time is dependent on the manufacturers inventory and production schedule. While most orders are filled within 3-5 weeks,...
