May I ask if such a weapon actually exists?
I have found these two types of weapons, but the reliable information I can obtain is too limited.
Let’s all take a look and see if this can be included in our game.
The information I could find merely stated that they were derivative models of the Browning BAR automatic rifle, without providing any detailed data to explain it.
I think I heard that these things are Swedish or something.
And what about this weapon?
The information states that it was designed as a weapon for cavalry troops.
M1922
The M1922 light machine gun was the first major improvement to the M1918 BAR. It was produced in small quantities in 1922 and was mainly equipped for the American cavalry. The M1922 light machine gun is characterized by having a heavy barrel, with heat dissipation ribs on the barrel surface. A pair of adjustable-length tripods were installed on the barrel sleeve, a single tripod was added to the bottom of the stock, and there was a hinged support plate on the bottom plate of the stock to stabilize the gun on the shoulder during fully automatic firing.
That’s a Swedish Kulsprutegevär m/37 (shortened; Kg m\37). One of several Swedish adaptations of the BAR. It runs in 6.5 Swedish.
The first one might also be a Swedish model, but I’d need a picture of the magazine to confirm.
USA Attempt at BR2 bar No. ???
I’d love to see a BAR at BR2, even a slightly detuned rate of fire version if that would convince the Dev’s. 
The Lewis Assault rifle is decent, but the ROF is on the slow side. I’d love to see the Jungle BAR as well, BR 2 or BR 3, I would use it either level.
