Interesting video Terra. I was impressed that when he lifted the rifle out of the water, he did not point the barrel down and crack the bolt to drain water from the barrel. That used to be US Army procedure. When the M16 was going through trials, the procedure was modified to drain water from the barrel by pinting the barrel down and opening the bolt prior to firing. Reason for the change was that the bore was so small the water was retained by capillary action in the bore. That stretches science a bit, but you change the rules to achieve your objectives. As I said, interesting video and will have to seek out a dealer to put some fingerprints on your product.
