CMC Triggers AR-15 Lower Receiver Parts Kit (No Grip / No Fire Control Group) - 81500 - UPC 859464006062
Product Description
The CMC Triggers AR-15 Lower Receiver Parts Kit (81500) is a premium, builder-oriented hardware package engineered specifically for custom rifle staging. Designed for operators and builders who intend to install a high-performance drop-in trigger and custom pistol grip, this kit eliminates duplicate stock components while providing every essential Mil-Spec internal small part, spring, and detent required to complete a stripped AR-15 lower receiver.
Proudly manufactured in Texas from high-strength, heat-treated steel, each component in the 81500 kit is held to exact dimensional tolerances and finished in a severe-duty black finish for superior resistance against wear, corrosion, and severe field environment conditions. The package includes a standard safety selector assembly, bolt catch assembly, magazine catch assembly, takedown/pivot pins, buffer retainer, and a Mil-Spec trigger guard with roll pin.
Ideal for staging custom builds featuring CMC’s famous single-stage or two-stage drop-in trigger cassettes, the CMC Triggers 81500 Lower Parts Kit ensures smooth mechanical cycling, crisp detent tension, and uncompromising reliability for duty, competition, and tactical AR platforms.
