Advantage Arms .22LR conversion kit for Glock 17, 17L, 22, 31, 34, 35, and 37. This kit is in brand new condition. I installed this kit on my G22 and never got around to using it. Retail is $275.00. Asking $250. May consider trades. I would like another handgun, not really particular as to what. I can add cash to the deal to. Kit includes slide/barrel, one clip, and cleaning kit.
