They're full auto only, correct? No semi-auto setting? I can see ammo wastage being a big problem after the TDM. Not sure if/how they would be employed after that.

Full auto only from an open bolt, so even if you fitted sights or an optic, accuracy wouldn't ever be super.

After that, any firearm might be better than normal. Even with the high cyclic rate, you could probably squeeze off five-round bursts with practice. The big problem is that they aren't designed for use with SS-109 ammo (they use the primarily tracers, with the older M-193(?) as a backup) -- limits ammo availability.

Good point, though with the accuracy the 231 would probably be bringing to the table the "100 meters and in, wartime emergency only" guidance for 62 grain ammo through 1-12 twist barrels like the 231 and M16A1 wouldn't mean missing out on much.

I would love to make one of these, but after researching it, it looks like the parts are a bitch to find. It's one of those projects that would take you forever to piece together. Plus, I'm no gun smith. Now, if they made complete parts kits I would be all over this.
