Performance Advantages for the Shooter
-The Geissele SSF has a semi-automatic pull weight of about 4.5 lbs — 2.5 lbs on the first stage and 2 lbs on the second stage. The automatic pull weight is about 3/4 lb higher than the semi-auto pull weight. The pull weights and sear engagement are non-adjustable by the shooter but are adjustable by the armorer. Organizations may contact Geissele directly for custom factory modifications to the above.
-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 SSF trigger allows the shooter to slap through the semi-automatic trigger pull on close in shots but also set up a long range shot with a crisp trigger break. The automatic pull is a smooth single-stage that is ultra controllable.
-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 M4 hammer. The lightened hammer favorably decreases locktime and increases accuracy of the weapon, especially for snap shots.
