'Pawn Stars' Missile Guidance System Purchase 'Not Illegal,' Producer Says

The stars of the History Channel's reality show 'Pawn Stars' (History).

Sources confirm to FOX411 that the stars of the History Channel’s reality show “Pawn Stars” have purchased a guidance system for a missile used on F-4 Phantom fighter planes.

TMZ originally reported that Rick Harrison and his team made the deal for an AIM-120 AMRAAM missile last week, although the missile did not contain a live war head.

According to the website for the U.S. Air Force, the AMRAAM missile is a medium-range, active radar homing air-to-air missile, which uses high-explosive blast fragmentation.

It weighs 335 pounds and has a range of more than 20 miles. It was deployed in September of 1991.

The Air Force lists the price at $386,000. The amount Harrison paid for the missile system was not immediately known.

So is it legal for a pawn shop to purchase a missile system?

“As far as we know, the missile is 100 percent not illegal,” "Pawn Stars" producer Brent Montgomery tells FOX411. “One time, a grenade came in and Rick was like, ‘You have to get that out of my shop right now!’ It wasn’t live, but you never know. I can’t have people thinking that they can take grenades into the shop—ballistic missiles, OK—but no grenades!”

Several items from the Department of Defense and other scrap from the military is available for legal purchase via live and Internet auction. In fact, military enthusiasts can buy scrap from the government itself at govsales.gov, the official site to buy U.S. Government property.

But one person who has sold his share of military scrap says this purchase is unique.

“That is a weird thing, even for me,” Alex Kramer, vice-president of International Military Antiques, tells FOX411 about the “Pawn Stars” gang’s purchase. “I’m not sure if it’s something that someone would want to put on display in their yard, but people collect all sorts of things. The person who would want this would be similar to someone who collects the first Apple computers—they appreciate the technology and its place in history.”
