Your vector costs $500 more... That's more then a 'little'.
As for what to try... If you have an unloaded mag, and allow the carrier to slam, does it go fully in to battery or does it still hang? My fathers century hangs, but only on a full 40rd mag. Anything else is fine. My century was fine until I raped it for parts for my Baby Dragon from Jeff...
Use a flash light and check it all.
Also, remove the trigger pack, replace the end cap. Insert an empty mag and see if it hangs...
If it still hangs that would be magazine fitment with the bolt head dragging. The second test should only be done at the range and ouly assuming the previous test was successful.
With the trigger pack removed, place a loaded magazine in and drop the bolt to see if it successfully strips a round an goes fully in to battery.
With these tests, we can eliminate the trigger pack being the problem, and determine if it's the magazine fitting or the pressure on the bolt head from a full mag.
