President Biden made gun-related gaffes during a campaign-style event in Pennsylvania on Tuesday afternoon.

Biden traveled to Wilkes-Barre to promote his "Safer America" agenda, which is focused on deterring crime and helping law enforcement. Biden's policies are also geared towards toughening up gun laws and expanding background checks. 

During the speech, Biden made an unsourced claim about the speed that an AR-15 shoots bullets.

"Do you realize the bullet out of an AR-15 travels five times as rapidly as a bullet shot out of any other gun?" Biden asked rhetorically during his speech.

It is unclear what the president was referencing, but AR-15s generally do not shoot the fastest bullets. 

A June study by hunting gear retailer Field and Stream looked at the fastest rifle cartridges – and AR-15 rounds did not make their list.

Field & Stream listed .220 Swift, .257 Weatherby Magnum and .30/378 Weatherby as the fastest rounds, along with 224 Clark and .22 Eargesplitten Loudenboomer.

The .220 Swifts are not shot by AR-15s.

Each of those five cartridges varies from 3,400 to 4,600 feet per second (fps), according to the study. 

BIDEN BLASTED FOR MOCKING ‘BRAVE’ SECOND AMENDMENT DEFENDERS: 'YOU NEED AN F-15' TO FIGHT AMERICA, NOT A GUN

The .223 and 5.56 – two popular, high-speed AR-15 rounds – move around 2,700 to 3,100 feet per second. 

Biden also claimed that "AR-15s just rip the body apart," which is also inaccurate. Damage from a gunshot depends on the type of bullets used. 

Biden also ridiculed Second Amendment advocates in the Tuesday speech, sarcastically calling them "brave" for believing guns are a tool for self-defense.

"For those brave right-wing Americans who say it’s all about keeping America independent and safe, if you want to fight against the country, you need an F-15," Biden said mockingly. "You need something more than a gun."

EDITOR’S NOTE: A previous version of this report stated that .200 Swifts are shot by AR-10s and not AR-15s. Neither AR-10s nor AR-15s shoot the .220 Swift.
