Higher damage = more consistency and one-shots and range. And anyone that complains it’s OP can compare the stats to other rifles. Farquhar-Hill has this damage, but has 19 rounds. Compared to other TT rifles, it deals more damage and fires faster, but has 2 fewer rounds.
I don’t know what else I can say from this point. It would be a good weapon, and anyone who knows how to play the game would agree.
So here we have a problem of overthinking things. Leave the m1 grand alone, it’s in the most ideal position you could put it in. Since we’re on the topic of what would be a good br4 rifle, just give the US a ten round slr 44.
We also already have a BRIV M1 the M1 Grenade thrower which is complete trash at BRIV the M9 Grenade is useless against most BRIV vehicles and you only get a BrIII rifle to fall back on when it runs out of grenades.
