Tools for me at that time I had one diamond files so used some 1000 and 1500 grit wet dry paper wet with breakfree clp as a wet and a old ss scapper as a back up for the paper. A set of small screw drives will let find the right one for me adjust the rear spring for tension. Lost my little tool also.
This is the basic info I used to tune my trigger. There also some newer to me video about prestageing the accublade and loading it on the sear then pulling bottom of the trigger and get a lighter pull yet, low 5 or 6 oz. Got to try that yet.
Scope, Don't laught !! I bought one of these for my 10/22 when prices were lower but not at this price and found over time it work very well and order a second for the savage when the close out first started about a 1+ ago. Don't know if midways has any left in close out or not. But a couple have showed on ebay.
