I recently acquired a new in the box 10/22 stainless. Went and picked up a .22 scope to mount on it. Removed the set screws on top to install the supplied scope mount. First, second, and third ones were snug. Went to remove the last one and was finger tight. Installed the scope mount, and discovered the set screw that was loose had stripped out threads. How the heck did this ever leave the factory like this? Ugh.
