Geissele Super Semi-Automatic (SSA) Trigger

These are factory blems, however, the only thing that appears to be blemished is the boxes that they arrived in. There do not appear to be any visible blemishes on the triggers. All of the stamps and markings look great. I imagine that they put a "BLEM" sticker on the box since the box was damaged and they didn't feel it could be sold as new. The price of these have been discounted $70 on account that they are marked as "Blemished".

Super Semi-Automatic (SSA®) Trigger
The Geissele Super Semi-Automatic (SSA®) trigger is a semi-automatic only version of Geissele's Super Select-Fire trigger. The SSA is a non-adjustable, precision, two-stage trigger and allows precise and accurate trigger control throughout a variety of conditions and usage requirements. The SSA’s two-stage design allows the trigger to be light enough for accurate and precise shots, but forgiving enough for frenetic close in work.
 
The SSA is safety certified by Crane Naval Surface Warfare Center. It is recommended for demanding applications such as Law Enforcement use, dynamic environments, and mid-range carbine work.
