G43 is similar to M14 in night battles, but with a RoF skill instead of damage. Was quite usable as a starter night rifle, and better than nothing, but you should really try to get a better one.

Or SKS for short. Self-buffs RoF, but with too weak stats. Between G43 and M14 you have enough good low-rarity rifles to keep you supplied while you work on better ones.
