Justin Pearcy, 36, is charged with multiple felony drug and weapons offenses, said Pennsylvania Attorney General Michelle Henry's Office in a release.
Charges were filed after police executed search warrants on the second-floor apartment above a Hunting Park Avenue daycare center, as well as a vehicle parked on Pulaski Avenue, authorities said.
During the search of the alleged "stash house," investigators said they found fentanyl, methamphetamine, crack cocaine, and marijuana, along with $33,000 in cash.
Also seized were "multiple assault-style rifles" and several handguns, two of which had been modified "with a device that made the gun fully automatic," the Attorney General's Office said. Another was reportedly fitted with a silencer.
Authorities believe the "stash" is "tied to a trafficking operation."
"In communities across Philadelphia, the scourge of guns and drugs continues to pose a grave threat,” city police Commissioner Danielle Outlaw wrote in a statement.
"This arrest, firearms seizure, and dismantling of a drug trafficking operation serves as a stark reminder of the dangerous nexus between narcotics and firearms."
Pearcy was arraigned early on Friday, June 30 and his bail was set at $2 million, according to the release.
