I am not disputing the fact that it was a poor light machine gun , it is just I don't know enough about small arms to distinguish between a good and bad one. What are the strengths and weaknesses of the 1918 BAR?
For 1918 it’s good, for 1941 not so much.
In 1918 the BAR was the best man portable LMG fielded by the belligerents.Can I get more details on why? This is very vague.
The big question is what the role is.
Is it a light machine gun or an automatic rifle.
It falls between both categories in my opinion.
It has too small a magazine capacity to be useful in a light machine gun (20 round maximum magazine, 40 round for anti aircraft but that role was abandoned in the 20s) and too heavy to be a good automatic rifle which is the role that the Americans tried to use it in.
It's also important to note that it's too complex. To change barrels you need to go to the armourer. Comparable weapons had quick change capability which could be changed by the soldier.
The FN-D was a light machine gun, which would require a crew to serve it and change US squad doctrine quite a bit.It depend entirely of the role it is intended for :
If it is as a rifle, nothing, as the Garand is far better.
If it is as a light squad support weapon, adopt the FN model D
In 1938 there was a design study to get a new version of the weapon. In 1939 the US Army came out with the decision that any new version (a2) had to be fully interchangeable with the old version of the weapon. Old weapons would have to be able to be converted into the new weapon. This meant that they were limited and couldn't improve what they wanted to.What realistic changes could be made to it to make it a more useful gun for the US Army in the late 1930's-1942 if the US Army thought of it?

They couldn't add a rate suppressor or a new pistol grip or modify the magazine capacity.
This meant the benefits of the new version was limited.
The receiver and action are at the heart of the gun, so as long as you keep them the same a lot could be changed.Assume the US Army scraps that requirement, I am interested in what could be done with it if the US Army decides that the old version is obsolete and needs complete replacement.
At that point you might as well take it down in weight and make something like the WAR and issue 3-4 per squad:The receiver and action are at the heart of the gun, so as long as you keep them the same a lot could be changed.
Post war the FN MAG was created with the same action, but with belt feed.
You could take the BAR and make improvements like a quick-change barrel, weight cuts etc. I doubt the feed would be changed from box to belt though.
Invert the action and feed it like a Bren. Give it a bigger box magazine.
You end up with US version of the Bren.
