I built my Grendel with a UBR stock and I do really like it. I considered the PRS but for my purposes I did not need or want the amount of adjustment the PRS offered. Since the comb of the UBR is fixed, whether the stock is extended or collapsed, I can maintain a consistent cheek weld and eye relief with my scope. This can be said of the PRS as well but I wanted a stock that could reduce the overall length of my rifle. They are both fine stocks but, like most things, there is always a trade off; I opted for a little more compactness.
