Description
The CMMG Bravo is one of the easiest ways to stretch your range budget without buying a second rifle. It swaps the .22 LR bolt group in place of your standard bolt carrier, letting your existing 5.56/.223 AR-15 run inexpensive rimfire ammo. The whole process takes about half a minute and needs no tools, so you can go from your defensive load to plinking rounds and back again on the same day at the range.
Unlike a gas-operated setup, this kit runs on direct blowback and does not use the rifle's gas system or impingement tube to cycle. That keeps things simple and reliable, and it's also piston compatible, so it plays nice with a wide range of AR builds chambered in .223 Remington, .223 Wylde, or 5.56 NATO.
What Makes the Bravo Bolt Group Stand Out
This is the all stainless steel version, which is the reason a lot of folks reach for the Bravo over the base kits. Stainless holds up well against the sooty fouling that comes with rimfire ammo, and it wipes down easier when it's time to clean. Rimfire runs dirty, so a bolt that cleans up quickly is a real quality-of-life upgrade after a long session.
Getting the Most Out of Your CMMG Bravo Conversion
A little know-how goes a long way with any .22 conversion. CMMG recommends running a round-style hammer rather than a notched one, since notched hammers can cause function hiccups. For ammo, 36 grain copper plated round nose loads tend to feed and cycle the best. Plenty of owners report smooth running with quality plated stuff like CCI Mini Mags, and keeping the bolt clean and lightly oiled goes a long way toward flawless cycling.
Bottom line, the Bravo gives you real AR-15 handling and trigger time at rimfire prices. It's a smart pickup for new shooter training, backyard-adjacent plinking, or just logging trigger time without burning through pricey centerfire ammo.

Frequently Asked Questions
How hard is it to install the CMMG Bravo conversion kit?
It's about as simple as it gets. You pull your standard bolt carrier group out of your AR-15 and drop the Bravo bolt group in its place. No tools and no other modifications are needed, and most owners have it done in under a minute.
Will the Bravo work in my AR-15?
It's designed for AR-15 upper receivers chambered in 5.56 NATO, .223 Remington, or .223 Wylde. It runs on direct blowback and does not rely on your rifle's gas system, and it's also piston compatible. As long as your upper is one of those standard chamberings, you're good to go.
What ammo runs best in the CMMG Bravo?
CMMG recommends 36 grain copper plated round nose bullets for the most reliable feeding and cycling. Quality plated loads like CCI Mini Mags are a common favorite among owners. Bulk unplated or the cheapest budget ammo can be less consistent, so leaning toward decent plated rounds pays off.
Why choose the stainless steel Bravo bolt group?
Rimfire ammo burns dirty, and stainless steel handles that fouling well and wipes clean more easily than other finishes. Keeping the bolt cleaned and lightly oiled is the key to smooth, reliable function over long range sessions.
