Refinished my 10/22 stock, when I got done I couldn't find the takedown screw. I guess it got up and walked off my bench when I wasn't looking, either that or my 7 year-old "helper" got his little hands on it (like most of the stuff that goes missing from my shop).

Hoping maybe someone who has done the bigger screw upgrade on their 10/22 has one they don't need laying around.
