I have used PayPal on limited occasions for firearms parts purchases - mostly through Ebay. The main reason I use it is if I want to use their 6 months no payment/no interest option - it's very useful when funds are tight during certain times - and I always pay it off before any interest hits. That said, I recently got a peepee slap from them for a 'firearm' purchase. They didn't say what it was, or to whom it was made, but they locked my account for a day until I read and agreed to their terms again. I don't know what it was, it certainly wasn't a firearm, but it had to have come from Ebay, and their policies have been nearly identical for years. Funny thing is, if you read their policy on weapons/parts, it is intentionally written with vague language, leaving them room to interpret whether your purchase is 'allowed' or not. No idea what happened, but it irked me at PP a bit. If I could get the same 6 months no pay/no interest with another method, I would use someone else.
