I've had this mod on my gauge for some time. I never though of it much, but wanted to share the idea.
Doesn't make much of a difference as far as sling removal if you want to go without with the front being permanently attached to the extension, but the swivel being able to twist a bit at the rear helps with slinging the gun on and off a bit easier I find.
I had a few of these from an UncleMikes REM 870 Police kit. I use one on the mag tube clamp of my 18" Mag with the top folder and the other on the above 14".
Sorry for the crappy photos. I'll replace them when I have a better time with a camera.
