The Geissele Super Semi-Automatic trigger is the semi-auto version of the Super Select-Fire trigger. The precise two-stage design of this 4.5-pound combat trigger permits the ultimate in trigger control and accuracy. The Geissele SSA trigger is light enough for quick shots and suitable for close-quarter combat. You can also use the trigger for mid-range carbine operations and law enforcement.

Geissele was established in 2004 to manufacture high-quality trigger mechanisms for the AR15 platform. The triggers produced today are especially targeted towards military, law enforcement and competitive use. The first trigger designed by Geissele was so popular that the U.S. military put in a request for a similar product specific to the semi-automatic sniper rifle platform. The military was so pleased with the result that they made it their trigger of choice for M4-style carbine rifles.

Geissele SSA Trigger Gives You Precise And Accurate Trigger Control

The operation of the Geissele Super Semi-Automatic trigger is both smooth and fast. Installation requires no special tools and can be completed 3 to 5 minutes, depending on how handy you are. You will be pleasantly surprised at how well the trigger operates compared to a standard Mil-Spec trigger. One happy reviewer compared the difference to that of night and day. For additional ease of installation, you might want to consider the trigger fitting pin/tool. Anyone who is interested in the AR platform should definitely give this trigger a try.

Although the SSA trigger pull is not as light as match triggers, the performance is virtually the same. If you need a quality trigger for just about any application, the Geissele SSA trigger is your solution.
