Questions: #1 - What kind of steel are these made out of? #2 - What are the dimensions of the OEM Ruger 10/22 extractor? Comments: If these are made out of A2 tool steel, that would be great. Would be nice to know the OEM dimensions so customers can compare what they have in their guns and see if what you are offering would really provide a better fit. Offering some known custom sized extractors sounds like a concept long overdue to help fix the dreaded stovepipe problems!
