Beryl and the M4 are the strongest choices in their own ammo categories, but they do come with the most recoil and the higher amount of attachments needed to complete their kits. These drawbacks are what makes them balanced towards other ARs in their respective ammo categories. A scar-l requires less attachments and is easier to control. Making it more powerful or as powerful as an M4 would make the M4 no longer a viable choice. The AKM packs a punch but it comes with a lower rate of fire and 1 attachment slot, making it a unique weapon choice with pros and cons compared to Beryl.
