The following screenshots are the result of damage testing; the target wore a Carrier Rig (level 4 armor) in every test, and received only one shot directly to the torso. The damage done can be seen on the bottom right corner of each screenshot.
In this screenshot is the standard AKM from the Apex dlc. He received 23% damage.
In this screenshot is the CUP Weapons AKM. He received 44% damage.
To understand how ridiculous this is, the screenshot below is the CUP Weapons FAL which fires a 7.62x51 NATO. It dealt 37% damage-- that's 7% less than what the CUP Weapons AK's are doing.
In conclusion, they are clearly overpowered and must be balanced. I'd like to add that you should please review the damage that all your weapons are doing. Make sure that they match the standards of the Vanilla weapons damage according to their calibers, because these inconsistencies have been the cause of so much confusion.
EDIT: An additional thought. Please check the weight of all your weapons as well, as they are just as inconsistent between the vanilla weapons. For example, the vanilla AKM and the CUP Weapons AKM vary in weight by a huge margin.
