I worked in the Browning Gunsmith Shop during the time the BBR was rolled out, I saw thousands of them.
And I have seen a ton of broken/cracked fore ends on them. In late winter here it is ridiculously dry indoors and the aluminum does not give when the wood shrinks around it. Because the shrinking wood is not a uniform piece it shrinks around the aluminum and focuses the forces from the inside out to the inside corners... cracks happen...
