Up to the facility manager, however facilities are generally no OC and CC only with a state CC permit and lands/refuge sites are upto the refuge manager. In every refuge I have been to OC & CC both long gun and hand gun have not been a problem. In fact every refuge I have been to hunting was permitted, though heavily restricted.Fish and Wildlife Services
Facilities are no OC, CC only with a state CC permit, though this is upto the district & regional rangers. Out in the forest, I don't think they really care. Usually. Sometimes you get some really weird people there, but for the most part so long as you ain't shooting at them or at USFS structure/equipment/signs, they don't care.Forest Services?
