Overview
The CMMG .22LR Barrel & Bolt Group Kit features a 16.1-inch M4 profile barrel designed specifically for .22 LR caliber, allowing builders to convert their AR-15 to fire the smaller, less expensive .22 long rifle rounds. This setup not only ensures compatibility with standard AR-15 platforms but also provides a lightweight option ideal for training and plinking. You’ll often find this kit in .22 LR dedicated builds, making it a popular choice for those looking to enjoy the benefits of shooting with reduced recoil and cost.
