[QUOTE="SidecarFlip, post: 1730039, member: 39764"] Back when I built machine guns (I have the license btw), I built an MG42 sub gun from a machinable kit from DP Arms for a customer (he was a Class 3 C&R collector and the MG 42 qualifies as a C&R weapon). Interestingly, the MG 42 (Nicknamed 'Hitler's Buzz Saw' because the rate of fire unmodified makes the sub gun sound like a chainsaw with no muffler) comes with 2 barrels. Unlike a Browning, it has an air cooled tube (not running in water for cooling). The MG42 has 2 barrels and a unique dovetail barrel mount and hinged fore stock, so you can remove a hot barrel and insert a cool barrel, the job of the gunner's mate. Typically, to cool a hot barrel, troops would take the hot one off the weapon (after unpinning the fore stock and swinging it out of the way and toss the hot tube in a creek to cool it off or a bucket of water. That was SOP wth them. 8MM Mauser belt fed across the top of the action, rate of fire (unmodofed) was about 1100 rounds per minute. If you lightened the Mauser double claw extractor, you could reliably attain a 1500 RPM cycle rate. Cooling hot tubes has been around for ages. [/QUOTE]
