Overview
The Geissele Automatics Super Semi-Automatic Enhanced (SSA-E) is a two-stage trigger designed specifically for the AR-15 platform. This trigger features a smooth initial take-up followed by a crisp break, allowing for enhanced accuracy and control during shooting. It's particularly popular in builds utilizing a mid-length gas system chambered in 5.56 NATO.

Geissele Automatics Super Semi-Automatic Enhanced SSA-E Two Stage AR-15 Trigger ranked #46 of the 240 triggers builders added on GunPartPicker in August 2026. Builders have been adding it to their builds on GunPartPicker since February 2026. All time, it ranks #41 of the 456 triggers builders have added. Builds with this trigger are mostly chambered in 5.56 NATO (71%, then 6mm ARC 29%), nearly all on mid-length gas, and nearly all AR-15.
Availability is good: it was in stock at one retailer or another nearly every day in August 2026, and today the one retailer we track has it in stock. Prices barely moved in August 2026, holding around $250, so there haven't been real sales lately. Buying today, the lowest price is $250 at Primary Arms, which matches the best price we saw in August.

This trigger is a game changer for my AR build. The initial takeup is smooth, and that second stage break is incredibly crisp. Makes follow-up shots so much faster and more accurate. Definitely an upgrade over mil-spec.
