I need some help. I purchase a use Bushmaster AR 15 with a red dot scope on it and you can zero in at 25 yards and at 50 yard it would be 12 inches off. So though the scope was mess up so I purchase a new scope and rings, samething. Don't know what to do unless the barrel is mess up.
You can build these 10/22's for about $1200 with carbon fiber barrel. Cheaper if you go with steel barrel cheaper scope. I build them for squirrel hunting.
