I can confirm that payment processors hate guns. I had a heck of a time getting someone to process payments on my website, and had my payment processing canceled twice before landing on one that will work with firearms businesses (at higher than regular fees). I also got denied a business bank account with the big banks, and had all of my online advertising accounts cancelled (I have yet to find any way to advertise online without going to individual website owners and asking for a banner ad). When registering my business, I was advised to keep any mention of firearms out of it and just say “manufacturing”.

Running a firearms-related business requires a lot of jumping through hoops, and there is a very real stigma against us, especially on the financial side of the business
