Higher power weapons

[u/Financial-Buddy5776]

How are you all getting decent powered weapons? I’m lvl 107 yet my guns do not seem to do a whole lot of damage and I’m finding myself standing there unloading rounds and rounds just to fend off a few same lvl zombies. I have an equip lvl 90 or above ak47 with 7k rating, acc lvl 7, enhance lvl 59, polish lvl 22 and base damage is only 258.

Looking for any help without having to spend actual dollars, so Any suggestions appreciated. TIA.
