The Advantage Arms AAC17-22G5MOD-CA is a .22 LR conversion kit designed for Glock 17 and Glock 22 Gen 5 pistols, allowing shooters to train with affordable rimfire ammunition using their existing Glock frame. This California-compliant version features a 10-round magazine capacity and installs without permanent modification to the host pistol, making it ideal for high-volume practice sessions while preserving the manual of arms of your centerfire Glock.
