CMMG Bravo Conversion Kit Features The CMMG Bravo Conversion Kit replaces a standard AR-15 bolt carrier group with a dedicated .22 LR unit and the swap takes only seconds without requiring any additional tools or gunsmithing. Because the kit operates on direct blowback rather than relying on the gas system it functions independently of the impingement tube making it compatible with both direct impingement and piston-driven AR-15 uppers. This straightforward operating principle keeps the conversion reliable across a range of host rifles chambered in 223/5.56 only. Shooters gain an immediate way to run high volumes of cheap .22 LR ammunition through a familiar AR-15 platform. The Bravo model is built from stainless steel a finish choice CMMG notes is generally easier to clean than some of its other conversion kit options which matters given how dirty rimfire ammunition can run compared to centerfire loads. As the most affordable stainless steel CMMG conversion kit available the Bravo offers a practical entry point for shooters who want the durability of stainless without paying for a more premium finish. This makes the kit well suited to training plinking and introducing new shooters to the AR-15 platform at a fraction of the cost per round. For AR-15 owners looking to add a rimfire training option the CMMG Bravo Conversion Kit is a simple affordable upgrade for sale at GrabAGun.
