Trinity Triggers AR-15 Full-Auto BCG – Aurum Gold

.223 / 5.56 / .300 BLK Compatible

The Aurum Gold Trinity Triggers AR-15 Bolt Carrier Group (BCG) is designed for shooters seeking both performance and refined finish. Built with a full-auto M16 carrier profile, it delivers consistent cycling and reliable function across a variety of ammunition types. Compatible with forced reset trigger systems and high-cycle-rate applications

Manufactured from Mil-Spec 8620 steel and paired with a Carpenter 158 bolt, this BCG is engineered for strength and longevity. The bolt is shot-peened for enhanced durability, while chrome-lined internals reduce wear and simplify maintenance.

The advanced low-friction coating reduces resistance and carbon buildup, helping maintain smooth operation and consistent performance even under extended use.

Each unit undergoes High Pressure Testing (HPT) and Magnetic Particle Inspection (MPI) to ensure it meets strict quality standards.
