CMMG Mil-Spec AR-15 Trigger Kit - High-Performance Upgrade for AR-15 Rifles

A CMMG Mil-Spec AR-15 trigger kit gives you the core trigger components to build or upgrade your AR-15 with a reliable, M16-style semi-auto trigger. Whether you're assembling a mil-spec reproduction, completing a rifle build, or swapping in a fresh trigger group, this kit includes every part you need in one package—no hunting through parts bins or dealing with incomplete assemblies.

CMMG's mil-spec trigger kit is built to work with standard AR-15 receivers and delivers the familiar break and reset you expect from a mil-spec two-stage trigger. It's the practical choice for builders who want proven reliability without paying premium prices for match-grade triggers. The kit approach saves you money and hassle compared to sourcing individual components separately.

Drop this kit into your lower receiver and you'll have a functional, dependable trigger group ready for range work, hunting, or tactical training. It's also a solid starting point if you plan to upgrade further down the line—nothing here locks you into a particular platform or caliber.
