I bought a couple of 10/22 Ruger rifles when they were first in production and there were no aftermarket parts available.
The deluxe model was acceptably accurate, the standard not so much, even with quality ammo. Neither was anything to write home about.
I sold them both, and have never bought/owned another. Too many better choices out there. I have an older Mossberg 151Mb that will consistently shoot 5/8" or so for 5 at 50 with RWS ammo.
I am a bolt gun fan, and even my lower priced bolt actions [CZ 452 American] will shoot tighter than the Mossy, so the Ruger is not attractive to me whatsoever.
The Marlins are good guns, however, and there are other semi-autos that will make you happy.... Just not a 10/22 unless you want to invest more money in it.
Regards, Dave.
