Paul Harrell, a 58-year-old gun rights activist and well-known firearms expert, died on Tuesday after a long battle with pancreatic cancer, Sportskeeda.com reported.

Harrell was diagnosed with stage two cancer in July 2023 but told media outlets he was confident he would beat the disease and live for many more years. Reported.

Paul's brother, Roy Harrell, uploaded a video of Paul saying goodbye titled “I'm Dead” to his brother's YouTube channel: “Let's get right to it. As I record this today, it's December 20th, 2023. And I'm recording this to tell Brad… [Paul’s video editor] “I was instructed to publish it when I was dead, so if you're looking at me, I'm dead,” Paul said.

Paul said his cancer diagnosis had worsened and the cancer had “spread to my bones.”

“My time is running short,” he said.

Paul paid tribute to those who supported his work, from his YouTube followers to his Patreon donors. He asked his Patreon backers to “not stop supporting us anytime soon,” as “we expect a few staff members, mainly my brother, to continue to create content.” Towards the end of the video, Roy appeared and acknowledged his brother's death, saying he and his staff “will provide updates on the channel as this situation progresses.” Video editor Brad also acknowledged the death of his friend.

“Just learned and given permission to share that Paul has passed away – a true lion of men, a model of integrity, the father of the internet's guns and an example to us all. May he continue to inspire us and challenge us to do better and more,” gun rights activist and attorney Tom Grieve wrote on social media. (Related: US court rules machine gun ban unconstitutional)
