Im a Norwegian, so here's an insider
To be able to buy shotguns and rifles you have to take a hunter-class. This costs a fee, and takes 30 hours. It is insanely easy, and I slept through all mine.
After that, you go the police, pay even more fees, and can apply for a firearm licens, up to 5 firearms per 1 fee.
E.g: Rem 870 for Rabbit, another 870 stainless for waterfowl, Ruger Mini-14 for deer, and a Rem 700 for elk.
You can own weapons like stated above from you are 16 years, with your parents permit.
To be able to buy military style rifles like AR15, AUG, SIG SG551 SWAT, etc, you have to be a member of an IPSC club, and be atleast 18.
To buy handguns, you must be a member of a shootingclub that uses handguns, and must be atleast 21. You must also be an active shooter for 6 months prior to getting any licenses.
And then:
We cant get CCW's, the government outlawed the use of LEAD in shotgun-cartridges, making the price go way up. They'll outlaw lead in bullets soon I predict. There is also a new law pending, making 6 weapons the max you can own, for hunters, without documenting special needs.
In addition, the law now states that you can get a license for something, if you dont have anything that SUITS that need particularly.
E.g: You have a Rem700 for elk, but want a Mini-14 for Deer.
Right now, thats all good.
But, now the law may be changed, so that if you have a weapon that can LEGALLY be used for a purpose, you dont get another gun. So, if you have a Rem700, you are legally allowed to take deer, and wouldnt get the Mini-14. Understand?
Sorry for the long post.
Makes me mad too se my countrymen get disarmed.
