CMC Triggers Enhanced BCG – AR-15 .223/5.56 Black Nitride

Description

High-quality components and precise manufacturing make this CMC Triggers Enhanced Bolt Carrier Group a durable, reliable replacement or upgrade for AR-15 platforms chambered in .223/5.56. The design improves carrier geometry to reduce tilt and decrease frictional contact points, while the Black Nitride treatment increases wear resistance and lubricity. Components are manufactured and processed to Mil‑Spec dimensions and testing where specified, providing consistent fit and function in service use.

Key Specifications

• The finish is Black Nitride to improve corrosion resistance and surface lubricity.
• The carrier is made from 8620 steel with case hardening for component longevity.
• The bolt components are manufactured from 9310 case hardened steel and are CNC ground after heat treatment.
• The cam pin is a hardened 4340 steel component for increased fatigue strength.
• The firing pin is Mil‑Spec 8740 steel as specified in the product information.
• Components are MPI and HPT tested as part of quality control.
• The extractor uses a Mil‑Spec spring and O‑ring for consistent extraction performance.
• The carrier design includes enlarged forward ports and reduced contact points to lower friction.
• The assembly is optimized for suppressor use and short‑barreled configurations to improve dwell time and extraction.

The CMC Enhanced Bolt Carrier Group blends precision machining and robust materials to serve as a reliable operating core for compatible AR‑15 platforms. Its design reduces carrier tilt and friction while the Black Nitride finish and tested steel components deliver durability and consistent function under regular use. For shooters who prioritize reliable, well‑engineered components in maintenance or upgrades, this BCG offers a practical balance of refined geometry and proven materials.
