For those of you who aren't already familiar with the Armory, it's designed to be a compiled quick reference for equipment across all six 40k RPG systems - you can use it to find basic information on gear that matches what you're looking for, then refer to the source rulebook for the full description.
Credits: unnownrelic and eBarbarossa for their previous work on the Armory, and of course FFG for creating some of my favorite roleplaying games.
