Great adjustment - Blue Force Gear Vickers 221 2-to-1 Unpadded Sling, Standard Push Button Version w/Nylon Adjuster and Hardware

I’m 5’10” 155 pounds of twisted steel. I mounted this to an 11.5 at the back of the hand guard at the 1030 slot. “BCM mcmr10”
The rear is secured on the ejection port side of an sba3 brace. It carries comfortably with or without gear on. In and out of vehicles is a breeze. Across the back I have ran with it all the way tight. Not a lot of bounce if you’re used to running with a rifle. With it on the receiver end plate it sorta gets in your way when trying to find a high form pistol grip. But this is expected.
In 1 point mode it lets the weapon hang against your side under your armpit. This is good for admin work while standing. It’s also good for in and out of vehicles.
