DULUTH, Minn. (AP) -

Northland gun dealers are reporting a spike in military-style gun sales.

Pat Kukull, owner of Superior Shooters Supply, says they are out of semi-automatic rifles due to people "panic buying." Some buyers are afraid of possible changes the federal government could make to gun laws.

She says other guns are selling fast as well and she's never seen anything like it in her 35 years in business.

Glen's Army Navy Store in Grand Rapids ran out of the semi-automatic rifles by Thursday morning and operators aren't sure when more will arrive.

Scott Van Valkenburg is owner of Fisherman's Corner in Pike Lake outside Duluth.

He says the semi-automatic rifles are usually about 5 percent of his thriving gun business but last week sales were nearly half of his gun sales.
