I don't think side mag is much of a problem, it's likely more practical than either top or bottom one when it comes to prone shooting.

What are you thinking if not side mounted? On top like a light bren, traditional forward like FAL, or bullpup like RFB?

Not on top - would probably conflict with all the stuff which gets attached to P-rails

In the context of the Foresight stories, are P-rails really a serious concern?  Seems like a bit of precision machining that isn't really necessary.  If you want to add optics (which will remain fairly rare given the limits on optics manufacturing capacity in this era), a side mount could work, like the telescopic sight mount on the Bren.

I have to agree.

What sort of modular accessories are we talking here?

No image intensifiers and nightvision systems. No lasers or red dots.  Scopes are rare and expensive.  Flashlights are large, heavy and dim. Rifle grenades and cup dischargers replace UBGL.

Basically all that's left are ergonomic accessories.

Well, there is one very well established cartridge, that would have done the job pretty flawlessly, allowed larger mag-capacity, longer range, flatter trajectory, less recoil, and not least consumed less resources, and that is the 6.5 x 55 Swedish.

I can see the utility being a standard attachment point for gun manufacturers and scope mount designers, it wouldn't need to be full length like modern ones.  

As far as scopes being rare and expensive, it's just a matter of priorities. If any major nation wanted a "rugged enough" ~3.5x PU like scope as standard for all riflemen, it could be done with concerted effort and expansion of infrastructure.  Unfortunately that's a hard sell prior to war footing, even if common wisdom at the time recognized the benefits.

You are right - I was being a bit dozy. What I should have said was that the top-mounted magazine got in the way of the sight line. Yes, you can mount the sights to look past the magazine (as in the Bren) but that makes it very difficult to use left-handed (or impossible, as in the Bren). 

Also, don't forget that we are talking here of an automatic rifle rather than an LMG (an FG 42, in effect). There were several LMGs which had top-mounted magazines, but I can't offhand think of any successful rifles.

The 6.5mm Swedish was arguably the best MG/sniper round to have seen extensive service. However, it has a big case - wider as well as longer than the 7.62x51 NATO - so there's little in the way of weight saving. According to some figures I have, it weighs 23 g with a 9 g bullet: the 7.62 x 51 weighs around 24 g (M80 ball); the .276 Pedersen appears to be around 19-20 g. In terms of recoil energy when fired from rifles of the same weight, the Pedersen is roughly 50% of the 7.62x51.

Well, not to be pessimistic, but I could easily see your British FG-42 ending up chambered for the original .276 cartridge, the one the P14 was supposed to be in. "The Paras and Marines need to engage the enemy at the longest possible range, old boy".
