To much lock tight - Troy Safety Selector Assembly, Direct Thread, Ambi, Semi Auto

On my screw there was lock tight. Before I could tighten the screw all the way ended up stripping it. Had to drill it out. Another customer hnd the same experience of having to drill it out. I would suggest buying a safety that doesn't use a screw. Also as a left hand shooter I would not recommend because the long side sill digs in to your hand
