CMMG MIL-SPEC TRIGGER KIT AR15

Description

The CMMG Mil-Spec Trigger Kit is a straightforward, dependable choice for anyone building an AR-15 from scratch or replacing a worn factory trigger group. It replicates the geometry and function of the original M16 trigger assembly, adapted for semi-automatic operation, which means the parts dimensions and fitment will be familiar to anyone who has worked on a standard AR-15 lower receiver before.

The single-stage design means there is no take-up or staged wall before the break — the trigger travels and fires in one consistent motion. This suits shooters who prefer a predictable, unambiguous feel, particularly for general-purpose or defensive builds where a staged pull can introduce hesitation. It is not a competition trigger, and it does not try to be; the value here is in reliability and interchangeability with a known standard rather than a tuned pull weight or minimal reset.

The kit ships complete with the hammer, trigger, disconnector, all three springs, and both hammer and trigger pins, so no additional small parts are needed to finish the lower. Drop-in installation follows standard AR-15 lower assembly procedure without modification to the receiver. For a first build or a budget-conscious spare parts kit, having every component sourced from a single manufacturer to a consistent specification removes one variable from the assembly process.
