Description
Rimfire ammo is one of the easiest ways to shoot more without burning through your budget, and the CMMG Bravo .22 LR AR Conversion Kit lets you do it on the rifle you already own. Instead of buying a whole second gun, you swap out your standard 5.56/.223 bolt carrier group for this drop-in unit, pop in a .22 LR magazine, and you're running rimfire through the same trigger, optic, and controls you already know. When you want your centerfire rifle back, the swap reverses in seconds with no tools involved.
What the Bravo Kit Brings to the Bench
The heart of this setup is an all stainless steel bolt conversion assembly, chamber adapter, extractor, and firing pin, so the parts doing the work are built to hold up and clean up easy. It fits most mil-spec upper receivers chambered in 5.56 NATO or .223 Remington, which covers the vast majority of AR-15 rifles and pistols out there. The kit ships with three 25-round polymer magazines designed specifically for the CMMG system, giving you plenty of capacity for a long afternoon of steel or paper.
Getting the Most Out of Your CMMG Bravo Conversion
A little ammo know-how goes a long way with any .22 conversion. CMMG recommends 36-grain plated-nose bullets for the best cycling, and a round-style hammer runs smoother than a notched one. Shooters who follow that guidance tend to report solid reliability, with plenty of folks running hundreds of rounds across multiple rifles once things are broken in. It's a favorite for new shooters, backyard plinking, and training on steel at close range without chewing up your targets.
Between the low recoil, the quiet report, and the money you save on ammo, this kit makes it easy to justify more trigger time. Keep your skills sharp year-round on the same platform you carry and compete with.

Frequently Asked Questions
How hard is the CMMG Bravo kit to install?
It's about as simple as it gets. You remove your standard 5.56/.223 bolt carrier group, drop in the Bravo conversion unit, and load a .22 LR magazine, no tools required. Most folks have it swapped over in around 30 seconds and reverse it just as fast when they want their centerfire rifle back.
Will this conversion kit fit my AR-15?
It works with most mil-spec AR-15 rifles and pistols chambered in 5.56 NATO or .223 Remington using a standard upper receiver. That covers the large majority of AR platforms out there. As long as your upper is mil-spec, you should be good to go.
What .22 LR ammo runs best in the CMMG Bravo?
CMMG recommends 36-grain plated-nose bullets for the most reliable cycling. A round-style hammer also runs smoother than a notched one. Sticking to those two tips goes a long way toward consistent feeding and function through the kit.
Do I need to change my barrel to shoot .22 LR with this kit?
No barrel swap needed. The .22 LR rounds fire straight through your existing 5.56/.223 barrel, so nothing else on the rifle changes. Keep in mind rimfire is dirtier than centerfire, so give the bore and bolt a good cleaning after your range sessions.
