Just a few thoughts: Looks like an ordinary, run of the mill AR-15. I watched it in lo-res, so I couldn't see if there was a happy switch on the side or not. I would think that a .308 AR would be a little bit better in that situation, or is that just me? Warning shots! Bam-bam-bam-bam-bam-bam-bam-bam... Et al, empty mag. I liked the sandbagged position, but it looked like they ran out of sandbags and didn't have enough for the stern deck area where he was shooting the most from. I don't think the skids would provide enough protection for my tastes. Just my observations. I'm not a blue water sailor, so if I got anything wrong, please be kind when pointing out any mis-observations.
