REQ issues with Anvil's legacy items

I’m having issues unlocking some of the permanent req’s from the anvils legacy update. I’m missing the COG DMR. COG SMG, and the Dampener DMR. These reqs are all rare, but silver packs are only rewarding me 3000 RP and no permanent unlocks. Any help would be appreciated.

Certain Rare REQs, despite being rare, seem to only be able to come out of Gold Packs. Once Silver packs start refunding you RP, switch to Gold, even if you have some Rare REQs left to unlock; they will get unlocked via Gold packs, eventually.
