Never having actually handed one, let alone fired one my opinion is limited to just that...what it's worth. But, I WAS infantry for decades and SA instructor for longer than I care to recall...and frankly want nothing to do with such a rifle. Neat to study and perhaps fire for curiosity but as Peter points out, the collection of small parts are not for infantry in the field under duress or fatigue, let alone darkness.
This one falls into the same category as the Johnston rifle, where the designer thinks it's a great idea and perhaps a few others that don't need to actually use it. The young men that do need to use it and deal with it soon reject it when shown... The reason they seem to climb to the heights of a wonder weapon is because they never did come to use and be proven a dismal failure.
Yes. The FN was the proper thing...
