Rugers have always been a crap shoot. Some shoot and some don't the ones that don't much of the time you can make them better but they may never be really good. Others that are pretty good you can make very good with a few mods.

After about 40 tries I have a few that are really good. If you want for sure awesome out of the box. Skip the headache and buy a Freedom Arms.

To try: Leupold base and rings $45 drill and tap Smith $40 cheap scope $60

If it shoots good. Add Belt Mtn pin and Wolf springs. If not sell it and buy another one.
