Back in the earlier daze of TFL, we had a thread on favorite full-auto. My choice was the old Korean-era halftrack, with a "bucket" in the back with four .50s mounted on it. Just firing two at a time (it's good to always have a couple of guns with full belts, at all times) in the "fire a burst of six" mode is a real hoot. All four at once, and in sustained fire, is downright orgasmic.
Any way you slice it, the Big Fifty is an attention getter--at both ends!
