We rarely sell parts for the post-1964 model 70, but we had several of these, so here they are. This is a swivel base for a post-1964 Super Grade rifle. These are original factory Winchester pieces in very good to excellent condition. These bases have the same footprint as the pre-64 Super grade bases and can be swapped in as a replacement for people who want to use the more modern "Uncle Mikes" style sling swivels on their pre-64 Super Grade rifle.
We use the NRA Modern Gun Condition Standards Grading System for grading part conditions. You can read about it HERE
