The Geissele Super Semi-Automatic (SSA) Trigger is the semi-auto only  version of a select fire trigger that Geissele makes for customers in  the U.S. Special Operations community. The SSA is a non-adjustable  combat trigger, it is not a match trigger. The second stage break is  like a carrot rather than an icicle. Suitable for Close Quarters Battle  (CQB) and mid-range carbine work, the Geissele SSA is also the perfect  trigger for Squad Designated Marksman (SDM) rifles. A short summary of  the Geissele SSA features and advantages follows.

Performance Advantages for the Shooter

  • The Geissele SSA has a pull weight of about 4.5lb: 2.5 lbs on the  first stage and 2lb on the second stage. The pull weights and sear  engagement are non adjustable by the shooter.

  • Trigger and hammer are made from quality tool steel.

  • Sear surfaces are cut by a wire edm machine. Sears cut this way are  very accurate and 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 his weapons ability to put the rounds where his  sight is pointing.

  • The Geissele SSA trigger allows the shooter to slap through the  trigger pull on close in shots but also set up a long range shot with a  crisp trigger break.

  • A full force hammer spring is used for quick locktime and positive  ignition of all types of ammo. No lightened hammer spring is used.

  • The hammer is lighter than a standard Rifle hammer. The lightened  hammer favorably decreases locktime and increases accuracy of the  weapon, especially for snap shots.

Advantages for the Armorer

  • The Geissele SSA is a simple design that is very similar to the original Rifle trigger. The number of parts is identical.

  • 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 dissembled for cleaning (no rivets or staked parts)

  • The trigger can be installed without removing the safety

  • Sear engagement is pre-set 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 Geissele SSA is a 2 stage trigger where there is generous  overlap of the sear surfaces which contributes to safety and a low  tendency of any inadvertent movement of the trigger to discharge the  weapon.

  • The Geissele SSA has a patented pseudo sear that is almost identical  to the standard Rifle single stage sear. However, this secondary sear  has surfaces that never touch during normal operation. This sear  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, abrasive environments that cause wear.
