Geissele’s SSA-E X Trigger is a perfect addition to an DMR-type AR platform, as well as any setup that requires accuracy and reliability. This non-adjustable drop in trigger features Nanocoating on the body and hammer for natural lubricity and excellent resistance to corrosion and wear. The SSA-E X Trigger is two-stage, the first stage is exceptionally smooth with a light take up, followed by a crisp break at the second stage.
