This Sear from Zenith Firearms is a direct-fit, semi-automatic-only fire control part sized for Zenith’s MKE-manufactured firearms line. The sear holds the hammer cocked under spring tension until the trigger releases it, firing one round per trigger pull. This is a standard semi-automatic part — it does not add, enable, or convert to fully automatic fire.
