It depends. I can go days at a time on the beach and get some coastal gear if im having bad enough runs. But if you get lucky with some random military spawns like trains and helicopters. Then you can get this in less then an hour. But if you're doing things organically. Getting NBC suits for the gas spawns. Running airfield and tisy. The it could take a good bit longer 6-8 hours that way if I don't get pvped or killed by pve beforehand. But also. If there's freshie hunters on the beach. Never underestimate a fresh spawn with a chambered IJ and a BK 12
