If you want to shoot your AR without breaking the bank on centerfire ammo, this CMMG Bravo conversion kit makes it simple. Just swap out your existing 5.56/.223 bolt carrier group with the Bravo unit and you're ready to fire inexpensive .22 LR ammunition. The kit comes with everything you need: a precision-machined stainless steel bolt assembly with integrated recoil spring, plus three 25-round FDE polymer magazines.
The beauty of this conversion is how straightforward it is. You remove your standard bolt carrier group and drop in the Bravo assembly, then you're good to go. No permanent modifications, no gunsmithing required. The kit works with any mil-spec AR-15 upper receiver, regardless of gas system type, so whether you run a carbine, mid-length, or rifle-length gas system, you're covered. When you want to switch back to 5.56, just swap the carriers again.
The Bravo features all-stainless construction, which is important because .22 rimfire ammunition leaves a lot of fouling and residue. Stainless resists corrosion better than carbon steel and wipes clean more easily after a range session. That said, this kit appreciates regular cleaning and moderate lubrication. Keep it from getting too dry, but don't over-lubricate or the residue will gum up the works. Most users report running a light amount of lube works best.
The included FDE polymer magazines hold 25 rounds each and feature a steel wire spring with polymer follower for reliable feeding. Color-coded FDE construction helps you distinguish these from your .223 magazines. For best results, CMMG recommends 36-grain copper-plated round nose ammunition, which tends to feed more reliably and creates less fouling than lead or other options. Round-style hammers work best with this kit; notched hammers can cause cycling issues. After a .22 session, running a magazine of .223 through the rifle helps burn off residue and function-checks the system.
Installation takes about a minute. Pop the back pin on your AR, remove the charging handle and existing bolt carrier group, keep the charging handle in place, and insert the Bravo conversion unit. That's it. To switch back to 5.56, simply reverse the process. No modifications to your rifle are needed.
CMMG recommends 36-grain copper-plated round nose .22 LR ammunition for optimal performance. Many users report good results with Federal Auto Match, CCI Mini Mags, and Winchester Wildcats. Avoid using lead bullets as they create excessive barrel fouling.
The Bravo conversion works with any mil-spec AR-15 upper receiver chambered in 5.56 NATO or .223 Remington, regardless of gas system type. It functions with direct impingement, piston systems, carbine, mid-length, and rifle-length gas tubes. However, a round-style hammer performs better than notched designs.
.22 LR ammunition produces heavy fouling, so cleaning after each range session is recommended for best reliability. Thoroughly clean the kit, upper receiver chamber, and breech area. Many users also fire a magazine of .223 through the rifle after a .22 session to clean out residue from the gas tube and verify function.
