CMMG Bravo AR-15 Rimfire Conversion Kit with 22LR Magazine - Stainless Steel

The CMMG Bravo AR-15 rimfire conversion kit transforms your existing 5.56 NATO rifle into a dedicated .22 LR trainer without permanent modification. Drop the conversion unit into your mil-spec AR-15 or carbine, swap out the bolt and carrier group, load the included magazine, and you're ready to drill fundamentals on a budget. This is how serious shooters log high-volume practice rounds on grip, trigger control, sight picture, and follow-ups while keeping ammunition costs in check—the centerfire ammo stays in the safe.

Built from stainless steel and fully assembled out of the box, the Bravo handles the abuse of frequent range sessions. CMMG engineered it to run in most AR platforms, including piston-driven uppers, though it performs most reliably with round-style AR hammers; notched designs can occasionally cause feeding hiccups. The system is compatible with standard .22 LR ammunition; CMMG recommends Federal 36-grain plated round-nose loads for optimal reliability.

Whether you're a competitive shooter refining your speed and accuracy between centerfire strings, a new shooter building muscle memory without flinch, or a hunter maximizing trigger time before season, the Bravo is a no-fuss way to keep your primary rifle in your hands. No gunsmithing required—installation is a five-minute swap that leaves your AR's receiver untouched.
