Google and YouTube has plenty of info....to get me "informed" I definitely don't want a sling around my neck on a bias....done that....never ever again
If you like it by all means....you can keep it
My gadget puts the muzzel up and safe pluse it frees up both hands and prevents my rile from leaving my shoulder until I want it too
All while using a traditional 1" leather sling
But.....since the Frankenstud is not for sale and was made to fill my needs.....it works perfectly
