The M1 carbine was famously used with it’s 15 round magazines that saw wide use throughout the gun’s service, but starting 1944 when the M2 carbine was introduced, along with it’s 30 round “banana” magazine, a decent number of M1 carbines used these larger capacity magazines. I think that it could be an interesting BR3 rifle for the US to have something similar to the VG 1-5, and would be quite easy to make as well, just replacing the 15 for the 30 round magazine used in the M2 carbine.
I like the VG 1-5, and although I didn’t like the 320 it at least hit at 9.6 when maxed, so it was not as pathetic as the M1 Carbine. Now that they are gonna get a ROF buff, I might somewhat actually like the M1 Carbine finally, and love the VG. I would like to see a version of the VG 1-5 in BR2, however to make it accurate it should have the 10 round magazine which I wouldn’t love, but could get used to it.
