Magpul UBR users- your expertise needed

[ElectricFactory]

My Magpul UBR arrived today with the stock mostly pre-assembled with the exception of the proprietary buffer tube. Once the Magpul buffer tube is installed to the lower receiver, can the UBR stock assembly be directly fitted onto it as it arrived ? Or must it be further disassembled in order to install ?

Did yours come with instructions?

The entry tube isn't exactly UBR specific, but its not the more common A1/ A2, or carbine length either. The stock can be installed without doing anything else, but pulling the lower section off makes it a bit easier.

The buffer tube goes onto the reciever, and the rest of the stock slides on and secures with a screw into the rear of the tube. If you've got wide stubby screwdriver, you could install that with the stock extended, but otherwise it's probably easier to slide the lower portion of the stock all the way off.

Sorted it out, mounted it, positively love the stock.
Thanks to all for for the helping hand.
