Last week the California Highway Patrol (CHP) announced that they arrested Michael Jay Kamfolt, a 40-year-old conservative activist who has an underground bunker containing a cache of 'illegal weapons,' ammo, and body armor. 

After receiving tip about an illegal marijuana grow operation, CHP Air Operations conducted a flyover of the property located in the city of Anderson, located around 150 miles north of Sacramento in Shasta County. 

Authorities conducted a month-long investigation of the property owned by Kamfolt, after which CHP executed a search warrant at the location on Jan. 20. 

And while they didn't find any weed being grown, officers recovered 13 firearms - including three AR-style assault rifles, one of which was a "ghost gun" without a serial number, along with a sawed-off shotgun and two firearms that had been reported stolen, one in 2016 and the other in 1978. 

A 'ghost gun' can be assembled at home, which is usually milled out of a hunk of aluminum or 3D printed. 

The bunker, equipped with power, ventilation, a concrete floor with built-in drainage, and the necessary supplies to grow weed, also contains a home gym, armchair, television, and workbench with a Bennington flag.

Investigators also found roughly 10,000 rounds of ammunition - an amount not uncommon among enthusiasts and preppers, including armor piercing rounds, 30 high-capacity magazines, and four soft-body armor vests. 

"During the search, officers discovered an underground bunker accessible through a 100-foot-long culvert," reads a press release. 'The bunker was equipped with power, ventilation, a concrete floor with built-in drainage and the necessary supplies to cultivate marijuana."
