The Geissele SSP trigger installs in the same way that a Mil-Spec trigger is installed and uses a standard .154” trigger and hammer pin so it will fit in any Mil-Spec stripped lower receiver. It features an M4 style curved trigger bow for maximum ergonomics and trigger control. This trigger will pair nicely with your designated marksman rifle whether it is a 5.56/.223 AR-15 rifles or a .308 AR-10 pattern rifle. Each trigger is precision EDM wire cut from heavy duty S7 tool steel with a durable black oxide finish giving you the reliability and durability you can depend on.

When building or upgrading your AR-15 rifle, one of the most important components is the trigger. There are many triggers out there so you must ask yourself what are you are going to do with the rifle. Are you going to use it for plinking at the range, home defense, hunting, competition, or long-range precision shooting? The answer of this question will help you to understand what trigger you will need. The Geissele Automatics Single-Stage Precision (SSP) M4 Curved Trigger is designed for precision target shooting and is even a great option for hunting. The first truly single-stage trigger offered by Geissele has absolutely zero take up and breaks at a light and crisp 3.5lbs to cut out as much human error as possible when taking long range shots where the slightest movement can make you miss. It also features a short and tactile reset so you can quickly engage targets whether you are hog hunting or competing in mid to long range target shooting. Install the Geissele Single-Stage Precision trigger in your AR-15 or AR-308 pattern rifle and be confident that you will make those long-range shots when you need to.

Geissele Automatics manufactures confidence, offering quality triggers and components for the warfighter and competitor. They were established in 2004 with the mission to build the highest quality, reliable triggers for competition and their first trigger, the Hi-Speed National Match trigger, was so popular that they were asked by the Department of Defense to produce a select-fire trigger for the United States Special Operations. Again, it was a success and Geissele decided to bring a semi-automatic version to the civilian market for law enforcement and personal protection.
