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.
