Specifications

The CMMG, Inc Hammer Trigger Pin is a standard .154-inch diameter pin designed for AR-15 platform rifles. It is made of hardened steel, offering durability and resistance to wear. The pin is specifically designed for use in rifles and is intended for installation in AR-15 lower receivers. The AR-15 is the only gun model for which this pin is recommended.

Design & Ergonomics

The CMMG, Inc Hammer Trigger Pin features a basic, cylindrical design typical of standard AR-15 trigger pins. The steel material provides a durable, heavy-duty feel.

Durability & Maintenance

The CMMG, Inc Hammer Trigger Pin, constructed from hardened steel, is expected to last for thousands of rounds with proper maintenance. Maintenance is minimal; regular cleaning and light lubrication are sufficient to prevent rust and corrosion. Given its simple design and robust material, it is highly durable and requires little attention.

The CMMG, Inc Hammer Trigger Pin does not come with any additional accessories. There are no customization options available directly for the pin itself. However, it is compatible with a wide range of aftermarket triggers and lower receivers designed for the AR-15 platform. It will work with almost all triggers from brands like Geissele, TriggerTech, and more.
