^Thats the PDF of the manual.
My first 10/22 gave me feed issues but I think it was the glossy finish they used on the all weather 351- serial # set. My new one has never given me one issue its all weather 353-.
My older brother has spent a bunch of time modding/tinkering with his. Its a tack driver and beautiful. Mine is completely OEM.
There is an auto bolt release mod you can do fairly easy if you are mechanically inclined. Its the only thing I do to my 10/22s. Look for it on Youtube.
