Normally a good ar 15 gun cleaning kit - Leapers UTG AR15 Cleaning Kit, 5.56/.223

This product is normally a good AR15 gun cleaning kit. I have in the past, purchased this kit by LEAPERS. But this particular kit had one rod section that was improperly milled or drilled such that component pieces would not screw into the end. (Chamber brush and others). Every other part worked fine and was in good shape except for one small part, (the shortest cleaning rod extension). So, I returned the entire package per the instructions given to me by Optics Planet. It's a shame because this is low technology manufacturing. It is not hard to make this well. You cannot blame Optics Planet because the defect is small and hard to notice until you open the package and assemble the pieces. It is a shame because in the U.S. we have given up our manufacturing base. I'm looking forward to my refund. Thanks!!!
