FYI, rolling an insert on a flat surface will help you spot any high points. Use a mill bastard file to remove excess material. This will allow the insert to slip fit into a Stanchy bored barrel, sans o-ring.
ty's inserts tend to run at the high end of the OD tolerence, and high end on length (i have one thats .03" longer)
usually the lasering will kick up a burr and be the high spot, high grit, wetsand paper will do the trick as well
