Ballistic Engineering AR Core Atrius-Compatible Curved AR-15 Trigger

The Ballistic Engineering AR Core Atrius-Compatible Trigger (Ballistic Engineering part no. ARCORECRATR) is a curved-shoe single-stage AR-15 trigger built to fit Atrius-pattern lower receivers. Built by Ballistic Engineering, this version of the Core line uses the same lightweight, no-adjustment design as the standard Core trigger, machined to the fitment needed for Atrius-pattern components. The curved shoe gives a familiar, traditional finger placement. It is a purpose-built option for owners running an Atrius-compatible lower who still want a straightforward Core-line trigger.
