There was the TRW Low Maintenance Rifle, an open-bolt full-auto-only rifle which looked like a cross between an M60, an FG42 and Home Hardware square tubing that was designed to be dumped to anti-communist guerillas in Vietnam, it was abandoned at the same time as Vietnam

The FG42 was the first one that came to my mind, too. Probably just because it went into "mass" production, whereas most other early designs were prototypes only.
In terms of discussion, I don't know where you would find that. As demonstrated above, the idea was well established before the AR15. The STG45, the EM1 and EM2 bullpups also come to mind as pre-AR15 examples with the muzzle-to-butt inline design, and the resultant requirement for very high sights.
The Johnson Light Machine Gun might be viewed as a transition species, as the barrel, action and recoil assembly were in-line from the muzzle back through 3/4 of the stock, but for some reason the buttplate was then mounted below the bore axis, taking away the in-line advantage right at the end.
