The M4E1 Pro Series Lower Build Kit featuring the Schmid Top Shelf 2-Stage High Polish Nickel Boron Trigger is purpose-built for AR-15 enthusiasts who demand smooth, consistent performance from the ground up. This two-stage trigger delivers a clean 4.5 lb take-up followed by a crisp 2 lb break, offering precise control for accurate shooting. The high-polish nickel boron finish enhances both durability and responsiveness, reducing friction for an ultra-smooth pull.
Designed exclusively for the AR-15 platform, this complete trigger assembly includes the nickel boron trigger, hammer, disconnector, and all necessary springs (anti-walk pins sold separately). Paired with Aero Precision’s rugged M4E1 PRO lower receiver, finished in anodized black and marked “Cal Multi,” this kit provides a lightweight, reliable, and American-made foundation for any serious AR-15 build.
