If you have access to a power Mitre saw , just make sure your stock is laying square on the table when you make your cut . Then try for fit . A shower shoe , makes a nice economical pad for it too . Just trace , cut and glue on ! Contact cement works great . Oh and don't worry about finding another wood 10-22 stock , they are a dime a dozen , every gun shop has a few laying around , as so many were replaced with synthetics .
Don't forget to have your liberals spayed or neutered !
