Magpul UBR install guide and pictorial review

[Stickman]

Congratulations, you have now installed your UBR, and you are ready to function test and test fire your weapon. However, there is a little more that the UBR offers.

The UBR uses two QD mounts to enable front or rear of the stock sling mounting. These QD mounts can be swapped to either side.

To remove the QD mount, insert an Allen wrench into the large side, and turn. There are Allen head screws on both sides, so if the screw spins freely without loosening, use an Allen wrench on the other side as well to lock it down.




Looking at the below picture, you can see a male and female side to the QD mounts.




Once you have them setup the way you want, use your Allen wrench(es) and tighten everything back down. It doesn't get much easier than this to configure a weapon for lefties.
