I have 4 slings, 3 of them one point, and this is the best of all of them. I say that not to imply that the other slings are bad, but to say that this sling is simply excellent. The construction and design are very good, and I also find it to be very comfortable due to the design of the section that fits around your body.
It is unclear in the image on here, but the attachment point is a clip that is covered by an elastic sheath (so it will not mar the finish on your weapon); and it should snap onto most clip-on type sling adapters.
Another note, as people who have more than a passing degree of experience with Airsoft slings probably know, many of them are designed in a way that does not allow you to cinch them as tight as you may like, causing your weapon to hang lower than is desired. For this reason it is also worth pointing out that this sling can be made quite snug, and allows you to carry your weapon closer to your body, and thus more securely.
-Good fit on all but the slimmest users
-Quality, smart clip design
