Great fast sling
This is an excellent sling! Much faster and more convenient than the military loop sling. Build quality is outstanding. The different settings let you get it dialed in just right. You have to experiment a little, everyone's biomechanics are different.
I should say though, the instructions mentioned trying to get the sling high in the arm, but I found this to be ineffective. I saw videos of James Yeager and others hooking it just above the elbow and that seems to work a lot better for me. The only person I saw using it high was that instructor from Gunsite.
