Unless I'm missing something, there's way too little information to make meaningful choices with regards to the roguelike aspect.
What do the unlockable components do, and why should I buy / save up for them? What categories (primary, secondary, precision, defense, etc.) do the unlocks fall under? How many components are currently available in each category? What does Cc mean in the Secondary weapon bias?
Once you communicate all this and more to the player, then maybe the whole sense of "ooh, I'm tipping the scales in my favor / adding strong components to the RNG pool" will be stronger.
