The 10/22 is so highly sought after not because it has been perfected by Ruger for the past 60 years, it is because it is a handy, fun rifle with acceptable accuracy and good reliability out of the box, as well as the fact that it is such an easy rifle to customize. Since Ruger took some time in really capitalizing on modifications to the 10/22 all these years, the aftermarket has expanded to much greater than the factory could even offer. I would recommend shooting your rifle for a little bit just to get used to it, and then consider what you may want to do to it. Personally I find that the most effective and useful basic modifications are an extended magazine release catch, trigger components/trigger, and a scope of some sort. Next on the list would be a different barrel and stock. There are so many different options for the 10/22, and most of them are simple to do and much less expensive than similar modifications to a centerfire semi automatic rifle making the 10/22 a popular choice for tinkerers and those who enjoy working on project guns. A good way to look at it is the 10/22 is the "AR-lite" when it comes to aftermarket. I'm not postive what range of odifications are legal in your country, but I would assume since none of them would change the semi automatic status that most would be accepted. You'll come to see that while handy and a hoot to shoot, the 10//22 is usually not in the same league accuracy wise as a good .22 bolt gun, so you may find yourself wanting to accurize it and tune out some of the slop. Looking forward to hearing what you decide to do!
