The file 'Ruger 10/22 Hybrid Picatinny Top Rail 3D Printer Model' is (stl) file type, size is 57.7KB.
My Holosun 510C did not fit on the original Ruger 10/22 top rail. But since I also installed TSR200RL tech sights, I needed a hybrid solution with the picatinny rail in front and the ruger rail in the back.
