I have fired the BAR quite a bit.
I am also a big fan of the M1 Garand, and have shot them a bunch as well.
I have shot the Thompson, and the M1 Carbine.
Baised on that, IF I had been in WWII I would want a BAR, striped down, no bipod, no handle for most uses in most places...
In the cities, for building to building, and indoor use, the 45 ACP Thompson is a good choice, maybe better, I like the 45 ACP for up close for sure, but even then I could use a BAR with good effect...
A Garand would be OK as well, but I am just not a fan of the M1 carbine...
