Geissele Automatics Triggers

Performance Advantages For The Shooter
Our triggers and hammers are made from quality S7 tool steel. The sear surfaces are cut by a wire EDM machine which makes the very accurate. The non-directional surface finish of the wire EDM gives a smooth trigger pull without the associated grittiness of directional machining marks left by a milling cutter.

The initial force needed to start the disengagement of the sear surfaces is low, and the force linearly increases at a low rate. This helps the shot to fall at the initial point of aim and aids in building shooter confidence in the weapon's ability to put the rounds where your sight is pointing.

A full-force hammer spring is used for quick lock-time and positive ignition of all types of ammo. No lightened hammer spring is used. The hammer is lighter than a standard AR15 hammer. The lightened hammer favorably decreases lock-time and increases accuracy of the weapon, especially for rapid shot and rapid follow up shots.

Advantages For The Armorer
The number of parts to a Geissele non-adjustable trigger is identical to a mil-spec trigger. There are no adjustment screws to come loose. All springs are captive; they will not get lost during disassembly in the field. The entire trigger can be disassembled for cleaning (no rivets or staked parts). The trigger can be installed without removing the safety.

Sear engagement is present from the factory. Hammer and trigger pins are a close slip fit into nominal receiver holes so the trigger can be installed and removed with rudimentary tools. Triggers come with a slave pin for the trigger/disconnector assembly for easy installation.

Safety Advantages
The two-stage trigger has a generous overlap of the sear surfaces which contributes to the safety and low tendency of any inadvertent movement of the trigger to discharge the weapon. Geissele's non-adjustable triggers offer a patented pseudo-sear that is almost identical to the standard AR15 single stage sear. However, this secondary sear has surfaces that never touch during normal operation. This prevents the hammer from falling unless the trigger is pulled.

The secondary safety sear contributes to shooter confidence in dynamic/vehicle situations where a fellow shooter's muzzle may cover him. There is firm knowledge that even with the safety in the fire position the weapon can never discharge unless the trigger is pulled. Trigger timing is robust and parts have been sized to operate with a certain amount of wear to the working surfaces. The trigger is designed to operate in dusty and abrasive environments that cause wear.
