    Moving UBR QD Cups

    If you want to move the QD cups on the UBR stock, you unscrew the bolt and nut in them and then how is the best way to remove the cup? I tapped at from behind and before I got after it I wanted to a) make sure that they are moveable and b) the best way to drive them out.

    The hex screws and nuts don't have any structural function right? They just hold in the QD cups, right?

    Thanks

    You should be able to drive them out - they are a little hard to get going because the cups are serrated on the side that fits into the plastic of the stock... they are pressed in. Make sure you center / align them before you start tightening the bolts once you move them to their new location / side.

    That's what I thought, and I thought I had seen it in the UBR manual, but I didn't see it this time when I downloaded it. I have a tendency to push stuff to hard, so I wanted to make sure before I messed with it.

    I tapped it out from the backside to remove it, and used my vice (with some wood blocks) to gently squeeze it back in the other side.

    After you've removed the nut/bolt from the cup you can put your sling in the cup, set the UBR on the floor, stand on it, and pull on your sling. It'll pop out. Tap it in the other side using a non-marring mallet if you have one (hard plastic, hard rubber, rawhide, etc.) taking care to keep it aligned. Lather, rinse, repeat for the other cup if you're moving both of them.

    I'll be sure to have my video camera going when I do it, something isn't going to go flying. I do like the no tool method though.

    Definitely don't lose a tooth or an eye while performing this trick. If you do, be sure to get it on tape.
