Ballistic Engineering AR Core Atrius Trigger Features The Ballistic Engineering AR Core Trigger delivers a fixed 3.5 pound pull weight through a 1.75 degree trigger pull engineered to provide the shortest break and reset available for an AR-platform trigger. As a single stage design it offers a clean predictable break with no take-up stage to work through before the shot breaks. A2 tool steel internals give the trigger group the strength needed to withstand repeated dry fire and live fire cycles without premature wear. 17-4PH stainless steel bushings support smooth low-friction pivot points for the hammer and trigger contributing to the trigger s crisp feel. A patented disconnect mechanism and a full mass hammer spring work together to ensure reliable primer ignition across a wide range of ammunition including harder primers sometimes found in steel-cased or military surplus rounds. The trigger is compatible with the Atrius FRT giving owners of that system a drop-in upgrade path to a lighter more consistent pull. This straight trigger bow design gives the shooter a consistent finger placement point shot after shot aiding repeatable trigger control. AR-15 owners looking for a competition-grade trigger with a dependable short reset will find the Ballistic Engineering AR Core Trigger a strong upgrade over a standard mil-spec trigger.
