Clyde was said to have cut down the stock just past the buffer tube, shortened the
barrel of the B.A.R. and welded together three 20 round magazines to make it a 57 round
capacity. (causing the loss of three rounds, due to the weld marks between the magazines).
However, the theory of welding together three magazines would have not only placed the
magazines at an ackward angle, but the internal springs would no longer have the ability
to properly feed the rounds into the gun's chamber. Nevertheless, this weapon, with
the barrel shortened was a deadly combination. Image below shows a replica image
that I had created on the computer, showing how the scattergun would have looked
had it been possible.
