Oj I think I asked you this before but are you planning on making any Tommy's in .17mach2?
My Tommy kit is just a stock set, a complete Ruger 1022 barreled action assembly is needed to complete it.
So if you have a 10/22 in .17, it will fit right in there.
Also it will fit the AMT Lightening and a most other 10/22 clones.
All sizes and types of magazines will work.
