The Ballistic Engineering AR Core Trigger (Ballistic Engineering part no. ARCOREST) is a single-stage AR-15 trigger set to a fixed 3.5-pound pull weight, with a straight shoe. Built by Ballistic Engineering, the Core line is designed as a straightforward, no-adjustment trigger for shooters who want a lighter, cleaner break than a mil-spec trigger without needing to tune anything. The straight shoe favors consistent finger placement across the blade. It is a solid, budget-friendly upgrade for range and duty AR-15 builds alike.
