According to the talk show David is watching the night Iz tells him she's pregnant, it is late February 2005 and she said she conceived "a few weeks ago." Later in the film, a check given to Ralph is dated mid-September 2005, which is roughly 8 months later, but a few moments later in the film when Iz discovers David is selling guns instead of sheets, she says she's only 5 months pregnant.
In the chase scene in Iraq when the smuggler enters the truck, the back of the truck seems fairly empty aside from some crates stacked against the cab. A moment later when they are celebrating being rescued by the American army, the crates are against the back of the truck, which make the truck seem full.
According to news and talk shows seen on David's television the day before and after he started working for Efraim, it was late Feburary 2005. In voiceover, he states that he learned the business over the next six weeks, which would advance the story to mid-April 2005, but in a montage of him learning how to use the federal website, the synopsis for the Beretta webpage is dated in March 2006.
According to news and talk shows on David's TV when he starts working with Efraim, it is late February 2005, and when they go to Iraq, his voiceover says he'd been working with Efraim for six months, which would be around late August 2005, but the date entered on the ledger when Efraim gets paid in Baghdad is for a date in June of 2006.
On the shooting range, both Efraim and David remove their ear muffs. Someone as knowledgeable about guns as Efraim is would never do this. The sound of a gunshot in a confined space can cause serious hearing damage.
A David Packouz voiceover says that they went to Rock Island, Illinois, for a big meeting with military procurement officers, and a few seconds later a caption reads "Rock Island Armory." Rock Island Armory is a commercial entity owned by Arms Corporation of the Philippines, or Armscor. The military installation in Illinois is Rock Island Arsenal.
During the 'price tag sequence' showing American soldiers in Iraq the voiceover mentions M16 rifles, while the correct type designation would be M4.
When David and Efraim meet with Henri the arms dealer in Las Vegas, David's voiceover says "When Iraq hung Saddam Hussein for crimes against humanity, rumor was Henri sold them the rope they used." The scene is set in mid-2006, and Saddam was executed in December 2006. However, David is providing an after-the-fact overview to the entire story.
In real life, Efraim was obsessed with the movie Le seigneur de guerre (2005), not Le balafré (1983).
This is not a documentary, it is a film inspired by true events and Le balafré (1983) was chosen for artistic reasons as it provides synchronicity with the rise and fall from power in the world of crime in Miami.
The government website request for quotes for Beretta 9mm pistols refers to type 92, a civilian term. While the military designation for this firearm is M9, the contract in question was to procure pistols for Iraqi police forces, so the commercial designation for the Model 92 is appropriate.
During a phone call with Captain Santos, who is in Baghdad, David Packouz's voice-over says, "Berettas are an Italian gun, made and manufactured in Italy." He describes this as a problem because of Italian export restrictions to Iraq. While this may be true, it's also true that Beretta has manufactured the M9 (the U.S. military's version of the Model 92FS) in the United States (at their Accokeek, Maryland, plant) since 1985, so exporting firearms of U.S. manufacture might have been a solution to the problem, though this was not mentioned in the movie.
The point was that AEY had procured a contract for guns directly from Italy that met their specifications and probably involved some grey market wheeling and dealing, so going to a plant in Maryland would not make sense from a business standpoint.
When one of the main characters had a gun pointed at his head in Albania, the masked man holding him stood directly behind him. If the shot were taken, the masked man would have been seriously wounded (at least).
He wasn't shot though, and Henry was only pointing the gun at David to scare him - the final scene of the film makes this clear - so it's irrelevant where the gun was being pointed.
When David and Efraim are smoking from the bong with night-vision goggles on, the specks of dust in their masks are completely identical in all the reverse angle cuts (even though these are supposedly seen through two different pairs of goggles), showing that both angles were shot through the same lens or the same post-production effect was applied to all the shots in the scene.
Even if re-packing the AK-47 bullets into plastic bags allowed them to discard the boxes with Chinese writing on them, each bullet would have clear factory information and the production year on the head-stamp.
When Efraim is explaining bidding to David, a girl in pink bikini top with a guy in yellow shorts walk past them. Seconds later the same couple are seen coming towards them.
Wrong label on the aircraft.
When David is jogging in Albania, he's wearing Apple's earbuds with the longer controls which included the mic. These were introduced with the iPhone 3GS in June 2009, well after the story takes place.
When Bashkim's wife begs David Packouz for information about her husband, she is speaking Romanian, not Albanian.
