[LRRPF52]

Regardless, I still like the idea. It'd be sort of a magnum version of the 1970s 6mm SAW round. Imagine if the M14 and M60 had been chambered for 6x42 (or better yet, 6x43, without the 2.25" length restriction), there would never have been a need for the M16 and M249!

Other than the fact that the M14 and M60 have some of the worst reliability issues and most maintenance-intensive schedules of all the small arms I have ever used. Both those systems are a PITA to operate reliably, maintain with armorer support, and keep spare parts on-hand for. In short, they suck big time.

Now the SAW cartridge I do like, at least the concept of it, but it does push the weapon size envelope for an assault rifle. The Chinese have basically adopted that cartridge with the 5.8x42 in their QBZ95, LMG, and DMR. I've heard they're not happy with its downrange performance at distance though, but who really knows...
