What Happened to Marine Gun Builder
Rumors began to swirl in early 2022 when suddenly, Marine Gun builder’s website (marinegunbuilder.com) and his Youtube channel went completely offline.
Reddit threads were created and the Polymer 80 community wondered if MGB had been arrested, de-platformed, or visited by a three-letter agency(cough ATF).
It appears that none of this was true and MGB had finally decided to hang up his hat and the heat was not worth it.
While this can’t be verified obviously, Marine Gun Builder did eventually make a post on the /r/polymer80 subreddit explaining the situation and letting his paid subscribers know what was going on.

Finally, I want to reiterate – I am safe – we are safe. I provided the following statement to Mr. Crump for release: “Hi Mr. Crump – I can confirm I was not de-platformed. I recognize there will be lots of speculation why I chose to de platform myself. The thousands of Patriots in our community who trust me know I wouldn’t come to that personal decision lightly unless I felt it best. Those that don’t – well – they’ll do what they do best and troll the internet with wild theories. It was an absolute pleasure to have you on the livestream last week and the perfect guest for what would be the last one. Thank you for all you do Mr. Crump.”
Any speculation other than this is wrong!!!
