About Ray

Call of Duty has been my main since the CoD4 days, which means I’ve leveled more meta ARs to gold than I’d care to admit. These days I split time between ranked multiplayer and Warzone, and most of my writing is loadout- and meta-driven — which guns are actually worth the grind this season, which attachments do something versus which ones just feel good, and the fastest legit routes through camo challenges.

I sit around a 3.0 lifetime K/D, but I care less about flexing stats than about saving you the twenty hours of trial-and-error I already burned.

My guides stay current with the meta as it shifts season to season across Black Ops 6, Black Ops 7 and Warzone — no filler, just what works right now.

Maining since CoD4 · ~3.0 lifetime K/D · every meta AR gold-camo’d.
