Now he’s facing hefty charges.

A 550-pound Bronx gangster — nicknamed “Wobbles” — and his ring of nine gun runners were busted for smuggling dozens of weapons into the Big Apple on Metro-North trains, authorities said Wednesday.

The heavy-duty hustle was thwarted after William “Wobbles” Soler, 33, and his crew allegedly sold 93 guns to an undercover cop, according to a 367-count felony indictment filed in Bronx Supreme Court on Wednesday.

Soler — who posed shirtless, clutching guns in photos — and his cohorts bought the weapons on the street in Westchester, Maine and Connecticut last year, according to state Attorney General Eric Schneiderman. They stuffed them in suitcases before boarding the trains, and once in the Big Apple they flipped the firearms — including .22 caliber guns and semiautomatic rifles — for “several times” their original price, authorities said.

Soler — a tattooed member of the Bloods gang — was also nabbed for conspiracy to commit murder for plotting to kill rival gang members, authorities said.

Even his defense attorney, Brian Sullivan, admitted the charges were “pretty large-scale.”

The accused big-time gun runner also goes by the nickname Redrum — murder backwards, authorities said.

He didn’t show up to his arraignment Wednesday due to health trouble, Sullivan said. Instead, he was cuffed to a bed at the Rikers Island heath center known as “The Boat,” he said.

The tubby trafficker, who faces 25 years in prison, may have big problems if convicted. “I would think being a very large person would put him at a big disadvantage [in prison] because the cots and the clothing are all not made for someday that large,” Sullivan said.

According to the indictment, an NYPD officer bought 93 guns from the ring in 47 separate meetings at two Bronx apartments. Roughly a dozen of the guns seized had the serial numbers filed off, making the weapons untraceable.

Soler and members of the alleged ring face charges including felony conspiracy, criminal possession and criminal sale of firearms.

Among those also named in the indictment were Devon “Burnz” Fairburn, 27, of Brooklyn; Ronald “Piff” Snyder, 25, of Manhattan; and Princesequan “Saiko” Hunter, 29, Cadeim “Deim” Beckford, 20, Julio “Punn” Morales, 29, and Erick “Pilz” Ransom, 26, of The Bronx.
