Unfortunately, WE uses RS threads on the buffer tube. The one that comes with it is for WA GBBRs.
If you like that stock, you have to buy the real MAGPUL one. There was one for sale in the classified recently at around 120 I think...

WTF!? NO.
The genuine Magpul PTS UBR's buffer tube has some weird thread on it (WA?) that won't fit WE.
The ACM/ELEMENT UBR clone (like the one airsoftpartsshop sells) has RS threads that fit the WE M4 receiver perfectly.
The clone UBR will fit WE.
Here's mine
