There are a lot of variables that go into those ad network decisions. Are you in a red state or a localized area where guns are particularly popular? Are you friends likely to buy guns? Do you buy other crossover product categories that gun owners also tend to purchase (ex. certain survival or camping gear)? Lastly, price per bid and volume... If nobody else is targeting you, or not paying enough to target you, the untargeted ads might make their way to your feed if they're bidding high enough or if facebook is simply trying to fulfill their ad volume.
