Pawn Stars

TMZ spoke with Chum who tells us ... when he walked into the Vegas dealership Thursday, the guys wanted around $100k for the jet black whip. But Chum was able to drive off with the car for only $85,000.

TMZ ran into Corey Harrison in New York City yesterday, where he told us they unloaded the AIM-120 AMRAAM missile guidance system (pictured below) ... but he didn't divulge who he sold it to ... or for how much.

As least the Pentagon doesn't have a reason to sniff around their shop anymore ... for now.

TMZ broke the story -- Harrison was arrested in Big Bear, CA for battery and resisting arrest after a drunken confrontation with a local biker.

Now, officials at the San Bernardino County District Attorney's office tell us ... prosecutors have reviewed the Sheriff's report and decided there wasn't enough evidence to convict Harrison ... so they dropped the case.

Okay, we pretty much have no idea what we're looking at -- but we're told it's part of the guidance system used on an AIM-120 AMRAAM missile ... typically launched out of F-4 Phantom fighter jets.

TMZ broke the story ... the person who sold the parts to the "Pawn Stars" guys earlier this month claimed her father bought the parts LEGALLY at a military auction back in the '80s.

Harrison and the biker guy never came to blows -- but the footage shows the men in a heated verbal exchange inside of Murray's Saloon and Eatery late Sunday night after Corey had been doing some drinking.

The owner of the bar tells us Corey and the biker got into a verbal argument over something motorcycle-related ... but just when things started to cool down and the two men shook hands ... tensions once again flared and the guys decided to continue their argument outside.

As we first reported -- a security guard called police fearing things would get violent ... and cops arrived before things could get ugly. However, Corey was taken to jail for allegedly pushing the security guard, and then nudging a cop.

After Corey was released, we're told he returned to the bar and apologized to the owner for his behavior -- and bar employees helped dig his truck out of the snow.

Cops arrested Harrison on suspicion of battery with serious bodily injury and resisting arrest -- both misdemeanors. Law enforcement sources tell us Harrison was arrested at the bar.

Harrison was released from custody at 8:00 AM this morning.

UPDATE: Law enforcement sources tell us cops were flagged down by a security guard at the bar after Harrison had gotten into a verbal dispute with another patron ... and the guard feared the dispute could have gotten violent.

Cops tell us ... after officers arrived and spoke to both Harrison and the other guy, Corey pushed one of the security guards and slightly pushed an officer.

Officials claim Harrison was held in custody for several hours because he was drunk -- and needed time to sober up before he could be released.

A lawyer for Harrison tells TMZ cops asked him to apologize for the verbal spat at the scene, but Corey felt he did nothing wrong and refused.

Sources connected to the situation tell us ... two members from the U.S. Air Force Special Investigations Unit rolled over to Gold and Silver Pawn yesterday wanting to check out the AIM-120 AMRAAM missile guidance system and missile parts the guys purchased just last week.

We're told the agents wanted to make sure the system was no longer active -- and pulled it apart to ensure it did not contain any important information.

The agents also inquired about the woman who sold the missile guts to the "Pawn Stars" -- a woman who claims she inherited the stuff from her father.

The seller had maintained that her dad purchased the items at an official military auction during the '80s ... and we're told she had the proper court-approved paperwork specifying she could legally sell the parts.

Here's the best part -- we're told while the agents were inside the shop, they explained how they were initially put on the case after someone from the Pentagon called up wanting to know why they were out of the loop about a missile featured on TMZ.com.

When called for comment, a rep from "Pawn Stars" confirmed agents from the U.S. Air Force Office of Special Investigations did drop by the shop.

Sources connected to the deal tell us Rick Harrison and his team made the deal for an AIM-120 AMRAAM missile last week ... along with the "front part" of the missile.

And before you freak out -- we're told the "front part" of the missile did NOT contain a live war head ... obviously.

Our source could not confirm how much cash Rick shelled out for the parts ... but we're guessing they don't come cheap.

As we first reported, the engine suddenly burst into flames while a production assistant on the show was driving it back to the shop.

A rep for the show tells us they took the car apart and now they think it'll take $10k worth of work to get it up and running again. The car belongs to Old Man Rick, who tells us, "She's gentle and these young little bastards these days don't know how to treat anything with care. That boy drivin’ it, you can’t fix dumb."

Sources connected with the show tell TMZ, a production assistant was driving the car -- which belongs to Richard aka "The Old Man" -- and right before he made it back to the shop for yesterday's taping ... the engine suddenly burst into flames.

They haven't pinpointed the exact reason behind the miniature explosion -- but we're told, a loose fuel hose is probably to blame.

Our friends at SpyOnVegas.com shot photos of Rick Harrison, Big Hoss and Chumlee throwing around their hard-earned cash at Vanity nightclub in the Hard Rock Hotel & Casino on Saturday night.

No word on exactly how much money the crew dropped that night -- but judging by the shallow puddles of Washingtons all over the floor, we're guessing the gang was probably down around $43.

TMZ has learned ... somebody is actually trying to sell Robosaurus -- and Friday afternoon, the guys from the show "Pawn Stars" had an up close and personal meeting with the havoc-wreaker to check out the goods.

But don't get too excited -- Corey "Big Hoss" Harrison tells us the "Pawn" crew couldn't get close to the $5 million asking price ... and didn't make an offer because they didn't want the owner "to be offended."
