Geissele SSA-E Two-Stage Curved Trigger, Black Oxide

Description

Built on the chassis of the Geissele SSA, the Super Semi-Automatic Enhanced (SSA-E) is a semi-automatic-only, two-stage curved trigger intended for mil‑spec AR-15/M4 platforms. It preserves the robustness and reliability of Geissele’s combat-proven two-stage design while offering reduced stage take-up for improved shooting control. The SSA-E is positioned for precision-oriented semi-automatic applications such as designated marksman or precision AR builds where a non-adjustable drop-in trigger is desired. Per manufacturer guidance, these triggers are for mil‑spec AR15/M4 carbine rifles and are not compatible with Sig MPX/MCX or pistol-caliber carbine AR variants.
