This is by far the easiest means to get a blaster on a one point sling if it lacks existing sling mounts. It's very low profile and the components will not get separated on you. If you have rails you have a secure mounting.
It is a wonderful product and would be perfect for my blasters. I have a Proton, and was wondering if the mount would work on it and it does, albeit a little loose because the rail is a bit narrower than the mount, but it holds on well and works as a keychain holder too. I would 100% recommend picking this thing up if you are interested in a sling mount, or a keychain mount using a small carabiner clip.
