The SSA is a non-adjustable combat trigger that is a precision two-stage trigger and allows precise and accurate trigger control; it is not a match trigger. The second stage break is like a carrot rather than an icicle. The two stage design allows the trigger to be light enough for accurate precise shots, but forgiving enough for Close Quarters Battle.
It has a simple design similar to the original M16 trigger. There are no adjustment screws to come loose and all springs are captive, they will not get lost during disassembly. The entire trigger can be disassembled for cleaning and can be installed without removing the safety.
The SSA is safety certified by Crane Naval Surface Warfare Center. It is recommended for demanding applications such as Law Enforcement use, Close Quarters Battle (CQB) and mid-range carbine work.
