I've got to say this is a great sling. I just got back from a 4-day practical rifle course at FrontSight and used this sling exclusively. Slung pretty much from 8am to 6:30 pm everyday, well maybe an hour break for lunch and a few more short breaks here and there, but you get the point.

I bought the Snap Shackle rear and HK front. I mostly used it as a single point, but did go 2-point for a little while. Very easy to adjust and change with this configuration. Easy to get in and out of with the snap shackle. 

Overall great experience with this sling and I’d buy another one in a heartbeat.
