Manufacturer: Geissele Automatics, LLC 05-171
NOTE: This trigger fit LARGE PIN Colt rifles made prior to 2009 ONLY.
Geissele is known as the best AR-15 trigger available. Their line of match, 3 gun and enhanced grade triggers are used by professional shooters and Special Forces and in top end guns by manufacturers like Larue Tactical, POF and VLTOR. If you are looking for the finest trigger on the market, you have found it.
This is a large pin version of the Geissele Super Semi-Automatic (SSA) trigger for use in Colt AR rifles manufactured from 1990 to 2009. It is a semi-automatic-only version of Geissele Automatics’s Super Select-Fire trigger. The SSA is a non-adjustable combat trigger that performs like a match-grade two-stage trigger and allows precise and accurate trigger control. It is recommended for demanding applications such as Squad Designated Marksman (SDM) rifles, Law Enforcement use, and Close Quarters Battle (CQB) and mid-range carbine work.
Specifications and Features:
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 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. There is no lightened hammer spring used
The hammer is lighter than a standard AR15 hammer. The lightened hammer favorably decreases locktime and increases accuracy of the weapon, especially for snap shots
The Geissele SSA is a simple design that is very similar to the original M16 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.
