The “Let’s Go, Brandon” slogan, understood as a coded profane insult lobbed at President Joe Biden, has now found its way to a new level of marketing: weaponry.

First published by NBC on Monday, the Palmetto State Armory in South Carolina has begun selling a part intended for an AR-15-style assault rifle it calls the “LETSGO-15 Stripped Lower Receiver.” This part typically features a serial number, meaning it is the only element of an AR-15 rifle that must be purchased through a licensed dealer.

“The product description on the company’s website says the fire selector on the weapon part features three modes: “’F@ck!’” (Safe), “’JOE!’” (Fire), “’Biden’” (Full Auto),” the NBC report notes.

Other dealers, including Culper Precision, advertise their own product with similar sentiments online including an AR-15 magazine with an animated Joe Biden’s face replete with googly eyes.

“Yes it comes with Googeley eyes on both sides, no we will not ship one without googeley eyes,” the product description (included here unedited) states. 

The slogan emerged after an altogether bizarre moment at the Talladega Superspeedway in early October.

NBC reporter Kelli Stavast, during an interview with NASCAR driver Brandon Brown, who was fresh off his win at the speedway, suggested that loud chants heard from a booming crowd nearby were cheers of “Let’s go, Brandon!” In actuality, many were saying, “Fuck Joe Biden!” It is unclear if Stavast misheard the chants or not.

Since then, the phrase has become a favorite one of those on the right and has extended all the way to use by lawmakers in Congress, including Trump cronies like Senator Ted Cruz of Texas, who posted a picture of himself on Twitter last week standing with a fan bearing a homemade “Let’s Go, Brandon” sign. Senate Minority Leader Mitch McConnell’s press secretary, according to the Associated Press, has also retweeted a photo of the phrase emblazoned on a banner and hung near a construction site in Virginia. And Rep. Bill Posey, a Republican of Florida, from the House floor on Oct. 22, ended his remarks with a fist pump and a meek “Let’s Go, Brandon!”

Whether or not the FBI investigates the marketing of products like the one sold by Palmetto State Armory is not clear. A representative did not immediately return a request for comment.
