Review on Optimized Drill Return Spring Assembly by Uxcell by Edwin White

I need this part for a 41.5mm case. A part came with a diameter of 42.5 mm. This makes it practically useless as there is no easy/quick/safe way to reduce the OD to the desired size. Not to mention putting it in the suitcase later. For $7, there's no point in even trying. So it's basically useless. They need to do better quality control. Aside from the sizing issue, it looked well made, but a well made part that doesn't fit is less useful than a poorly made part that does.
