Check out Airsoftdepot.ca, they got every imaginable sling mount available.

Unfortunately, a lot of small airsoft dealers only want to sell guns. The little items, they are not interested in. They have to remember, if their customer goes to the competitor that has all the little pieces, and also sell guns, they can easily lose that customer in the future.

I won't name a particular dealer, but they don't even stock bb's. Because you don't need it.
