CMC AR-15 TACTICAL TRIGGER
While the CMC TACTICAL TRIGGER for AR15/AR10 rifles may not be the absolute best available trigger for the AR15 platform. It is in my opinion the best value in quality AR15 TRIGGERS and is able to go toe to toe with triggers costing $100 more. The CMC TACTICAL TRIGGER will exceed the expectations of all but the most discriminating AR15/AR10 shooters.
Geissele Automatics – Hi-Speed National Match Trigger
The Geissele Automatics – Hi-Speed National Match Trigger Fully adjustable trigger gives a smooth, two-stage pull with a precise icicle sharp break and ultra-fast lock time to minimize accuracy loss caused by gun movement during trigger pull. Set first stage pull weight by bending the legs of the trigger spring; set second-stage weight within a pre-set range by turning its adjustment screw. Another screw on the trigger lets you adjust overtravel for clean, crisp letoff. Lightweight hammer provides a 50% reduction in lock time over factory hammer, yet uses standard weight hammer spring to ensure sufficient energy transfer for reliable primer ignition, even on AR-style .308 weapons. Trigger shoe is positioned 1/8″ farther forward than factory shoe for comfortable finger position during the squeeze. All contact surfaces are wire EDM cut to exact dimensions for full, precise engagement free of unwanted play.

GEISSELE AUTOMATICS SSA TRIGGER
The GEISSELE AUTOMATICS SSA TRIGGER is without question one of the best non-adjustable combat AR-15 triggers you can obtain.
From the Manufacturer:
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 onthe 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 AR15 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 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. Hammer and trigger pins are a close slip fit into nominal receiver holes so the trigger can be installed and removed with rudimentarytools. 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 almostidentical to the standard AR15 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.
