GEISSELE AUTOMATICS
AR-15/M16/308 AR SSA & SSA-E TRIGGER

854014005007 100003620
Two-Stage Trigger With Ultra-Fast Lock Time; Adjustable & Pre-Set Models
Super Semi-Automatic (SSA) 2-stage combat trigger has a fixed 4½ lb. total pull weight, non-adjustable sear engagement, and additional safety features ideal for CQB and mid-range carbine work. A secondary “safety sear” captures the hammer if the primary sear accidentally releases due to hard impact, ensuring the rifle can fire only when the shooter actually pulls the trigger. Trigger pull is optimized for both deliberate, aimed fire and quick, “snap shooting.” The first stage builds gradually to 2½ lbs., with a 2 lb. second stage that breaks clean, so the shooter can stay on target throughout the pull. A lightweight hammer driven by a full-power hammer spring speeds locktime and delivers positive ignition of all ammo types. All contact surfaces are wire-EDM cut to exact dimensions for precise engagement free of play. Direct replacement for factory trigger; may be installed without removing the safety. Operation and parts layout is similar to the USGI M16 trigger for easy maintenance. All springs are captive to simplify field disassembly for cleaning. Hammer and trigger pins are a close slip-fit in nominal .154" (small pin) mil-spec receiver holes to enable installation with basic tools. Super Semi-Automatic-Enhanced (SSA-E) offers an even lighter, 3½ lb. total pull weight, making it an excellent choice for precision Squad Designated Marksman type rifles where both accuracy and reliability are critical. First stage builds gradually to 2.3 lbs., followed by a 1.2 lb. second stage with a crisp, “candy cane-like” break. A semi-auto-only version of the Geissele full-auto combat trigger presently used in the U.S. Special Operations community.

SPECS: Steel, black finish. Fits semi-automatic AR-15/M16 receivers with .154" diameter hammer and trigger pin holes. May be installed in AR-style .308 rifles that accept AR-15 triggers. Kit includes trigger and hammer assemblies, springs, hammer pin, tube of grease, and illustrated instructions.
