Advantage Arms Conversion Kit Features The Advantage Arms Conversion Kit swaps a Glock 17 or 22 Gen 4 pistol over to .22 LR using a purpose-built slide and 4.49 inch threaded barrel letting the host firearm s frame and trigger group stay in place. The threaded muzzle accepts a suppressor or compensator and Advantage Arms specifically recommends the Rugged Oculus and SilencerCo Warlock II Max for quiet range sessions. Two 15-round magazines are included so shooters can keep cycling through drills without constantly reloading. The recessed slide cut is machined for a variety of red dot optics giving shooters the option to train with the same sight picture they use on their centerfire pistol. Constructed from aircraft aluminum and finished in black the conversion unit is built to hold up to repeated range use while adding minimal extra weight to the pistol. A padded range bag is included for storage and transport keeping the barrel slide and magazines organized between trips. This kit does not include a handgun or red dot optic so it is intended for owners who already have a compatible Glock 17 or 22 Gen 4 frame. It is an ideal tool for building muscle memory teaching new shooters safe fundamentals or simply enjoying inexpensive .22 LR range time.
