Advantage Arms AAC17-22G3MOD-CA .22 LR Conversion Kit – Glock 17/22 Gen 3 (CA Compliant)

The Advantage Arms AAC17-22G3MOD-CA conversion kit transforms your Glock 17 or Glock 22 Gen 3 pistol into a .22 LR rimfire trainer. Designed for California compliance, this conversion upper replaces your factory slide assembly and allows economical practice with the same grip angle, trigger pull, and manual of arms as your centerfire Glock. Ideal for high-volume training, new shooter instruction, or plinking without the cost of 9mm or .40 S&W ammunition.

The kit features a machined steel barrel and a lightweight polymer upper assembly with an integrated adjustable rear sight. Includes one 10-round magazine to meet California capacity restrictions. Installation is tool-free—simply remove your existing slide and install the conversion kit on your Glock lower frame. The kit retains your factory controls and trigger mechanism. Note that reliability is optimized with high-velocity .22 LR ammunition; standard-velocity loads may require a break-in period.
