Advanced Arms Conversion Kit for Glock 19/23 Gen 5 - Model AAC19-23G5MOD

The Advanced Arms Conversion Kit for Glock 19/23 Gen 5 lets you transform your duty or carry gun into a dedicated .22 LR training platform—without buying a second handgun. This MOD series kit drops into your Gen 5 Glock 19 or 23 and converts it to rimfire, so you can shoot affordably, train newcomers safely, or dial in your fundamentals without the recoil and cost of centerfire rounds.

Whether you're a competitive shooter looking to run cheaper practice sessions, an instructor introducing new shooters to pistol mechanics, or someone who just wants a quiet, low-recoil way to keep your skills sharp, a .22 LR conversion kit is a practical addition to your shooting bag. The MOD includes everything you need to get running: a 4.5-inch threaded barrel, two 15-round magazines, and a range bag for transport. The upper receiver features a recessed cut designed to accept a variety of common red dot sight patterns, so you can mount your optic and train the way you actually shoot.

The threaded barrel opens the door to suppressor use if you run a can—the kit was engineered with suppressors in mind, and popular options like the Rugged Oculus and SilencerCo Warlock II Max pair well with it. At just 6.5 ounces, it won't burden your carry gun or range kit. Keep in mind that you'll need your own Glock 19 or 23 Gen 5 frame to use this kit; the conversion components work with your existing lower receiver.

Frequently Asked Questions

Will this conversion kit work with my Glock 19 or 23?

The Advanced Arms MOD kit is specifically designed for Glock 19 and 23 models in Gen 5. Make sure your gun is Gen 5 before purchasing; it will not fit earlier generations.

What suppressors work with the threaded barrel?

The kit was engineered to pair with rimfire suppressors. Rugged Oculus and SilencerCo Warlock II Max are specifically recommended, though other quality .22 LR cans should thread on. Always verify compatibility with your chosen suppressor and observe all local and federal silencer regulations.

Do I need to buy a whole new Glock to use this?

No. You use your existing Glock 19 or 23 Gen 5 frame as the lower receiver. The kit includes the upper components (barrel, slide assembly, and magazines) needed to convert it to .22 LR. Your current gun remains unchanged when you swap the conversion kit in or out.

Can I mount an optic on this kit?

Yes. The upper receiver has a recessed cut designed to accommodate various red dot sight patterns. You'll need to supply your own red dot; the kit does not include one.
