Repeated Weapons in REQ???

I’ve gotta know why I keep unlocking the Classic BR and the Recon AR in my silver packs (bought all there is to buy in the bronze packs)!!!
I’ve already got it, but its something that keeps popping up!

there’s different modifications for each loadout weapon. you’re just getting different versions with a slight enhancment.
for ex: the sentinel br can also have kinetic bolt, long barrel, silencer, recoil reducer, or energy bayonet. every loadout weapon is like this except the magnum.
