Ballistic Engineering AR Core 3.5lb Straight Drop-In AR-15 Trigger - Atrius Compatible

The Ballistic Engineering AR Core is a straight drop-in trigger built specifically for the AR-15 platform. Designed to install into a standard AR-15 lower receiver group without additional fitting, the Core is set up with a fixed 3.5 lb pull weight and a tight 1.75 degree trigger pull that delivers one of the shortest breaks and resets in the Ballistic Engineering lineup.

This version is engineered for Atrius compatibility, making it a turnkey replacement trigger for shooters running an Atrius forced reset trigger system. The straight trigger blade offers a classic finger-on-blade feel for a clean, predictable pull, while the drop-in cassette housing installs with standard AR-15 trigger and hammer pins - no gunsmithing required.

Whether you are assembling a new build, refreshing a worn mil-spec trigger, or pairing the Core with an Atrius installation, this drop-in trigger from Ballistic Engineering gives you a crisp break and a short reset in a true drop-in package.
