Geissele SPR Semi-Auto Enhanced (SSA-E) Trigger – AR-15/AR-10

The Geissele Super Semi-Automatic Enhanced (SSA-E) is a two-stage precision trigger designed for shooters who need match-grade accuracy from a semi-automatic platform. Built for precision rifle applications, the SSA-E delivers a crisp, light pull ideal for accurate shot placement at distance. The first stage provides approximately 2.3 lbs of resistance, breaking to a second stage that releases at around 1.2 lbs for a combined 3.5 lb pull weight. This refined trigger pull improves control and reduces anticipation, making it a popular choice for designated marksman rifles, SPRs, and competition AR builds.

Constructed from heat-treated tool steel with a manganese phosphate finish, the SSA-E is built to military durability standards while offering civilian precision. All Geissele triggers are precision wire EDM cut and hand-inspected. Installation is drop-in for most mil-spec AR-15 and AR-10 lower receivers, though some staked trigger guard pins or out-of-spec receivers may require minor fitting. The trigger includes detailed installation instructions.
