1. Can I upgrade my older Loop with parts from the new version?
While our Slings are completely modular, with tons of interchangeablity, some parts from the newer models won't fit onto the first two versions of the Loop because they used a different, larger webbing size.
The QD Swivel will work on Loop 3 forward. That's the one that came with the offset mount and used the Carbon Nylon sliders.
If you have an older model, that predates our Carbon Nylon sliders and hard mounts, the new mounts won't fit.
