We’re not really feeling it for a technical post this morning, so instead let’s introduce Andrew, a self-described “gun nut” and the personable host of the one-year-old GY6 Slo Mo video channel. Here is a loooong burst with a gun that solves a problem nobody has, a belt-fed full-auto AR in 9 x 19 mm.
This isn’t especially practical. If there’s something that needs a whole belt of 9mm at point-blank range, you fight it, we’re backing off and calling a fire mission. But it looks like fun and that’s reason enough to own a gun.
Actually, if you are interested in the Freedom Arms FM-9 belt-fed upper, he has a 20 minute full review, that answers pretty well “what it is,” without going deep into “what it’s for.” The quick-change barrel system (enabled by the gun being a simple mass-locked blowback) is clever and good.
We don’t think we want one, but we do think we understand it after Andrew’s video.
The feed mechanism is the now-customary MG-42 based design. Our guess, without examining the weapon, is that the reason that Freedom Ordnance wants you to load the belt with the feed tray cover down, and not up (mentioned at about 6:45 and 8:45), is because closing the feed tray with the bolt forward can damage the mechanism. It’s possible to design a feed system that can be safely close bolt-forward or -back — FN’s world-market machine guns are designed that way, by having a spring-loaded roller.
