In reply to Adriana Eyzaguirre:
These people hire out riffles http://northgreenlandhunting.gl/
But not sure if they only do it to people on the hunting tours they arrange.
there is no license requirement to own a semi automatic hunting riffle on Greenland.
From what i have seen, a riffle is not very good at scaring a polar bear.
The Danish Navy run a dog sledge patrol on the East coast, and there is an amazing documentary where a journalist and camera man went out for months with 2 guys from this patrol, and at one point they come across a polar bear, fire some riffle shots then a flare and the bear just don't care, so they put up camp and wait for it to go away.
Best way to scare of the bears seems to be dogs and lots of them.
