After what feels like years of meaning to but never really getting around to it I finally sat myself down and ported the weapons in the Skitarii and Adeptus Mechanicus Codexes over for use in Rogue Trader and the other games using that system.

Feel free to use in any campaigns you desire.
I'd also really like it if someone could go through and tell me how they feel about balancing and the like, if any weapon needs a nerf, buff, or complete redesign, as well as any other comments.
