if you you are too poor(like me) to buy tandemkross charging handle for your buckmark .22lr semi auto pistol here comes the 3d printed one.

at least pla+

included profile is to print pretty slow (max flow is restricted to 3mm3/s) to maximize toughness ~1,2h print time

hardware needed - m3x30(cut down to ~28mm) screws and nuts x2
